Given:

The mass of the cart is,

The acceleration of the cart is,

To find:

The force applied to the cart

Explanation:

The force on the cart is,

Hence, the force is 14.06 N.

The car is moving at approximately 12.5 meters per second.

The kinetic energy (KE) of an object can be calculated using the formula:

KE = 1/2 * m * \(v^2\)

where

KE = kinetic energy,

m =Mass of the object, and

v = velocity.

In this case, we are given the mass (m) of the car as 1600 kg and the kinetic energy (KE) as 125,000 J. To find the velocity .

Substituting the  values , we have:

125,000 J = 1/2 * 1600 kg *\(v^2\)

Now, we can solve for v by rearranging the equation:

\(v^2\) = (2 * 125,000 J) / 1600 kg

\(v^2\) = 156.25 \(m^2/s^2\)

Taking the square root, we find:

v = √156.25\(m^2/s^2\)

v ≈ 12.5 m/s

Therefore, the car is moving at approximately 12.5 meters per second.

With the knowledge of bearing, the airplane will be 24 degrees east of north relative to the ground. The correct answer is option d

Relative motion can be defined as a change of position of an object with a point or frame of reference which we may assumed to be at rest.

Given that an airplane whose airspeed is 190 km/h heads due north. If there is a wind blowing at 86 km/h from west to east, the magnitude of  degrees Ф east of north in which the airplane will travel relative to the ground can be known by using a trigonometry ratio.

The Y component is 190 km/h heads due north.

The X component is 86 km/h from west to east.

TanФ = Y/X

Ф = \(Tan^{-1} (\frac{Y}{X})\)

Ф =    \(Tan^{-1} (\frac{190}{86})\)

Ф =  \(Tan^{-1} (2.209)\)

Ф = 65.65°

The degrees east of north  = 90 - 65.65

The degree east of north = 24.4°

Therefore, the magnitude of degrees east of north in which the airplane will travel relative to the ground is 24° approximately.

Answer:

The difference in the calculated and measured velocity could be due to the fact that the motion sensor may not have been able to accurately detect the velocity of the block 1.0 second before the explosion due to the sudden change in momentum caused by the explosion. Additionally, the motion sensor may not have been able to accurately detect the velocity of the two pieces 1.0 second after the explosion due to the sudden change in momentum caused by the explosion. This could explain the 10% discrepancy between the calculated and measured velocity.

The resultant velocity of the man is 12.5 m/s N of E.

Velocity of the man, Vm = 7.5 m/s

Velocity of Ship, Vs= 10 m/s

Since, velocity is a vector quantity, it will have both the magnitude and the direction.

So the magnitude for the resultant vector can be calculated by using the formula

\(\sqrt{x^{2} +y^{2} }\) ; where x is the magnitude of the x-axis component and y is the magnitude of the y-axis component

i.e.

= \(\sqrt{Vm^{2} +Vs^{2} }\)

= \(\sqrt{7.5^{2} + 10^{2} }\)

= \(\sqrt{156.25}\)

= 12.5 m/s

Also the direction can be calculated by Tan\(\alpha\)

Tan\(\alpha\) = \(\frac{10}{7.5}\)

= Tan⁻(1.33)

= 58.9°

The angle between the resultant velocity and the horizontal axis is 58.9°.

Therefore the resultant velocity of the man relative to the water is 12.5 m/s towards NORTH-EAST direction.

Answer:

The difference between (a) and (b) is the deviation caused by the actual pulley not being a perfect solid disk. In (a), we took into account the additional frictional torque and calculated the more accurate moment of inertia. In (b), we made a rough estimate assuming the pulley to be a solid disk, which disregards factors such as the mass distribution and the presence of the axle. The difference between the two values is the deviation caused by these factors.

Sound waves are a type of mechanical wave that propagate through a medium, typically air but also other materials such as water or solids.

Frequency: the frequency of a sound wave refers to the number of cycles or vibrations it completes per second and is measured in Hertz (Hz).

Amplitude: the amplitude of a sound wave refers to the maximum displacement or intensity of the wave from its equilibrium position. It represents the loudness or volume of the sound, with larger amplitudes corresponding to louder sounds and smaller amplitudes corresponding to softer sounds.

Wavelength: the wavelength of a sound wave is the distance between two consecutive points in the wave that are in phase, such as from one peak to the next or one trough to the next. It is inversely related to the frequency of the wave.

Answer:

Where is the question this is only a statement therefore I cannot help you

Explanation:

Answer:

Its C

Explanation:

My teacher did it for me and it was right.

We can use the following data to get the values of acceleration and the distance covered at top speed:

Maximum speed is 20 m/s (v_max).

Time (t) = 21 seconds

(d) = 270 m is the total distance travelled.

Find the acceleration (A) first:

Applying the equation v = u + at

where an is the acceleration, t is the elapsed time, u is the beginning velocity, and v is the end velocity.

Given: The bus will begin at rest with an initial velocity of 0 metres per second (u).

The formula can be rearranged as follows:

a = (v - u) / t

a = (20 m/s - 0 m/s) / 21 seconds

0.952 m/s2 a = 20 m/s / 21 sec

Therefore, the acceleration of the bus is approximately 0.952 m/s².

Next, let's find the distance traveled at maximum speed (B):

Since the bus starts from rest, it takes time to accelerate to its maximum speed and then decelerate to stop. The distance traveled at maximum speed can be found by subtracting the distances covered during acceleration and deceleration from the total distance.

Distance during acceleration = (1/2) * a * t^2

Distance during deceleration = (1/2) * a * t^2

Distance traveled at maximum speed = Total distance - (Distance during acceleration + Distance during deceleration)

B = d - (0.5 * a * t^2 + 0.5 * a * t^2)

B = 270 m - (0.5 * 0.952 m/s² * (21 sec)^2 + 0.5 * 0.952 m/s² * (21 sec)^2)

B = 270 m - (0.952 m/s² * (21 sec)^2)

B = 270 m - 220.392 m

B ≈ 49.608 m

Therefore, the distance traveled at maximum speed is approximately 49.608 m

Answer: For question 1

131 is the correct answer

KE = 1/2 mv^2

Explanation:

Answer:

3.2 MN

Explanation:

Given that

Mass of the box, m = 52 kg

Initial velocity of the box, u = 400 m/s

Final velocity of the box, v = 0 m/s

Time taken for the collision, t = 0.0065 s

Using the equation of motion

V = u + at, we turn around and make acceleration, a the subject of the formula. Now we have,

a = (v - u) / t

a = (0 - 400) / 0.0065

a = 61538.5 m/s²

The acceleration(which is negative acceleration or retar.dation actually) is 61538.5 m/s². We then proceed to is this acceleration in the basic Force equation, to get the magnitude of force needed.

Remember,

Force = mass * acceleration

F = ma, we already have our mass and acceleration, all we do is multiply

F = 52 * 61538.5

F = 3200002 N or 3.2 MN

Therefore, the magnitude of the force that acts on the box during collision is 3.2 MN
