The driver of a car slams on the brakes, causing the car to slow down at a rate of 19.0ft/s2 as the car skids 195ft to a stop.
How long does the car take to stop?
What was the car's initial speed?
Answers
The time taken by the car to stop will be 4.53 seconds. The final velocity is zero and the initial velocity will be 86.08 ft./s.
What is velocity?Velocity is a vector quantity which measures distance covered per unit time. It is given that the acceleration of the car a is 19 ft/s². The distance it covered is 195 ft.
We have the expression for final velocity v initial velocity u and the time t with acceleration a as follows where the final velocity v for the car is zero.
0 = U - at
u = at.
The relation between time, acceleration and initial velocity with distance d is written as:
d = u t - 1/2 at²
= at² -1/2 at²
= 1/2 at²
Thus, t = √(2d/a)
= √(2×195 ft / 19 ft/s²)
= 4.53 s.
Initial velocity u = a t
= 4.53 s ×19 ft/s²
= 86.08 ft./s
Therefore, the initial velocity will be 86.08 ft./s.

what is the physics behind why electric parallel plates move from positive to negative
Answers
The physics behind the movement of electric charges between parallel plates is based on the principles of electrostatics. Electric charges are either positive or negative, and they are affected by electric fields.
Electric fields are created by a difference in electric potential, which is measured in volts. When a voltage is applied to a set of parallel plates, the charges within the plates will be affected by the electric field, and will move in response to it.
What are electric parallel plates?When a voltage is applied to a set of parallel plates, the positive charges in the plate connected to the positive voltage will be attracted to the negative voltage, while the negative charges in the plate connected to the negative voltage will be attracted to the positive voltage.
The movement of charges between the plates is also affected by the presence of any obstacles or resistances in the electric field, such as resistance in the wire. This can slow down the movement of charges and result in a decrease in the current flowing through the circuit.
In all, the movement of charges between electric parallel plates is the result of the electric field created by a difference in electric potential, and the movement of charges is called drift velocity. The movement is also affected by the presence of resistance.

A 1 000 kg car is pulling a 300 kg trailer. Together, the car and trailer move forward with an acceleration of 2. 15 m/s². Ignore any force of air drag on the car and all friction forces on the trailer. Determine (a) the net force on the car
Answers
(a) A 1 000 kg car is pulling a 300 kg trailer, together the car and trailer move forward with an acceleration of 2. 15 m/s² the net force acting on the car (and trailer) is approximately 2,795 Newtons (N).
To determine the net force on the car, we can use Newton's second law of motion, which states that the net force acting on an object is equal to the product of its mass and acceleration.
The total mass of the car and trailer combined is the sum of their individual masses: 1,000 kg + 300 kg = 1,300 kg.
The acceleration of the car and trailer system is given as 2.15 m/s².
Using Newton's second law:
Net force = mass × acceleration
Net force = 1,300 kg × 2.15 m/s²
Net force ≈ 2,795 N
Therefore, the net force acting on the car (and trailer) is approximately 2,795 Newtons (N).
This net force is responsible for accelerating the combined mass of the car and trailer in the forward direction. It represents the sum of all external forces acting on the system, such as the force exerted by the car's engine and the tension in the connection between the car and trailer.

Your answer appears to be off by a factor of 10n, where n is an integer value. Ensure you have represented the number in the correct units. Grade Summary Deductions 100% 0%
Answers
The magnitude of the electric field inside the capacitor is: E = 93.53 x 10^3 N/C (or 93.53 kN/C)
Describe Electric Field?An electric field is a physical quantity that describes the influence that an electric charge exerts on other charges within the space around it. It is defined as the force per unit charge that a test charge would experience at a given point in space, in the presence of an electric charge or charges.
Electric fields are typically represented by vectors, which have both magnitude and direction. The strength of an electric field is measured in units of volts per meter (V/m).
Electric fields are fundamental to understanding the behavior of electrical systems, including electronic circuits and power grids. They also play a critical role in the functioning of many natural phenomena, such as lightning, the aurora borealis, and the behavior of atoms and molecules.
Part (a) To find the charge on one of the plates, we can use the formula:
Q = C x V
where Q is the charge, C is the capacitance, and V is the potential difference.
Substituting the given values, we get:
Q = 0.072 F x 333 V = 23.976 C ≈ 2.4 x 10^-11 C
Therefore, the charge on one of the plates is approximately 2.4 x 10^-11 coulombs.
Part (b) To find the distance between the plates, we can use the formula:
C = ε0 x (A/d)
where ε0 is the permittivity of free space, A is the area of each plate, and d is the distance between the plates.
Solving for d, we get:
d = ε0 x A / C
Substituting the given values, we get:
d = (8.85 x 10^-12 F/m) x (0.29 m)^2 / 0.072 F = 3.56 x 10^-6 m = 3.56 micrometers (μm)
Therefore, the distance between the plates is approximately 3.56 μm.
Part (c) The electric field inside the capacitor can be calculated using the formula:
E = V/d
where V is the potential difference and d is the distance between the plates.
Substituting the given values, we get:
E = 333 V / (3.56 x 10^-6 m) = 93.53 x 10^3 V/m
However, the question asks for the magnitude of the electric field in newtons per coulomb. To convert from volts per meter to newtons per coulomb, we can use the formula:
1 V/m = 1 N/C
Therefore, the magnitude of the electric field inside the capacitor is:
E = 93.53 x 10^3 N/C (or 93.53 kN/C)

A car mass 600kg starts from rest moving uniform acceleration 0.2 m/s^2 after 60 seconds collides with stationary pick up van of mass 400kg gets locked with it and moves together with velocity 7.2 m/s
a) DOES THE PHENOMENON OF THE STEM SUPPORT THE PRINCIPLE OF CONSERVATION OF MOMENTUM? GIVE YOUR OPINION BY MATHEMATICAL ANALYSIS.
Answers
Answer:
The given phenomenon supports the Principle of Conservation of momentum.
Explanation:
law of conservation of momentum
Initial Momentum = Final Momentum
So, first we calculate initial momentum of the system:
Initial Momentum = m1*u1 + m2*u2
and we are given
m1 = mass of car = 600 kg
m2 = mass of van = 400 kg
u1 = Initial Speed of Car
to find the initial speed we use equation of motion
Vf = Vi + at
Vf = 0 m/s + (0.2 m/s²)(60 s)
Vf = u₁ = 12 m/s
u₂ = Initial Speed of Van = 0 m/s
Therefore,
Initial Momentum = (600 kg)(12 m/s) + (400 kg)(0 m/s)
Initial Momentum = 7200 Ns .........(1)
final momentum = m₁v₁ + m₂v₂
where,
v₁ = v₂ = final speed of car+van (both locked ) = 7.2 m/s
Therefore,
Final Momentum = (600 kg)(7.2 m/s) + (400 kg)(7.2 m/s)
Final Momentum = 7200 Ns -------- (2)
on comparing (1) and (2)
Initial momentum = Final Momentum
Hence, the phenomenon of the system supports the principle of conservation of momentum.

A small car moving at 20 m/sec collides head on with an oncoming large truck moving at 25 m/sec. Which vehicle undergoes the largest change in its momentum
Answers
Answer:
The truck will undergo the largest change in momentum if it has a greater mass than the small car.
Explanation:
The change in momentum of an object can be calculated using the equation:
Δp = m * Δv
where Δp represents the change in momentum, m represents the mass of the object, and Δv represents the change in velocity.
Since we are comparing the change in momentum of the car and the truck, we need to consider the masses of both vehicles.
Let's assume the mass of the car is represented by m_car, and the mass of the truck is represented by m_truck.
Since both vehicles collide head-on, the change in velocity (Δv) will be the difference between their initial velocities, considering that they are moving in opposite directions:
Δv = v_truck - v_car
Now, let's compare the change in momentum for the car and the truck:
For the car:
Δp_car = m_car * Δv
For the truck:
Δp_truck = m_truck * Δv
Comparing the magnitudes of the change in momentum, we can neglect the negative sign:
|Δp_car| = |m_car * Δv|
|Δp_truck| = |m_truck * Δv|
Since both Δv and Δp are positive values, we can conclude that the vehicle with the greater mass will undergo the largest change in its momentum.
Therefore, if the mass of the truck (m_truck) is greater than the mass of the car (m_car), then the truck will undergo the largest change in its momentum. Conversely, if the mass of the car is greater, then the car will undergo the largest change in its momentum.

where U is the potential energy in Joules, C is the capacitance in Farads, and V is the voltage across the capacitor in Volts.
In this case, we are given that the capacitor stores 9.40 x 10^-10 C of charge at 50.0 V. However, we are not given the capacitance value. Therefore, we cannot calculate the potential energy directly using the above formula.
To find the capacitance value, we can use the formula:
C = Q / V
where Q is the charge stored in the capacitor and V is the voltage across the capacitor.
Substituting the given values, we get:
C = 9.40 x 10^-10 / 50.0
= 1.88 x 10^-11 F
Now we can use the formula for electric potential energy to find the energy stored in the capacitor:
U = (1/2) * 1.88 x 10^-11 * (50.0)^2
= 4.70 x 10^-8 J
Therefore, the electric potential energy stored in the capacitor is 4.70 x 10^-8 Joules.

A helicopter (mass = 5000 kg) lifts 1475 kg of stuff (two people and packages). Let’s say initially the helicopter is hovering (v = 0 m/s). What thrust (force) is necessary for the helicopter to hover?
Answers
While it's carrying the passengers and packages, its total mass is 5000 kg + 1475 kg = 6475 kg, so that its weight is
(6475 kg) g = 63,455 N
In order to hover, the helicopter's thrust should match this weight.
