A woman is driving at a velocity of 12.74 m/s at an angle of 57° What is the Ycomponent of her velocity?

Answer:

10) The distance between the archer and the tree is 50.074 meters.

11) The speed of the banana when it hits the water is approximately 13.554 meters per second.

Explanation:

10) The arrow experiments a parabolic motion, which is the combination of horizontal motion at constant velocity and vertical uniform accelerated motion. In this case we need to find the horizontal distance between the archer and the tree, calculated by the following kinematic equation:

\(x = x_{o} +v_{o}\cdot t \cdot \cos \theta\) (Eq. 1)

Where:

\(x_{o}\) - Initial position of the arrow, measured in meters.

\(x\) - Final position of the arrow, measured in meters.

\(v_{o}\) - Initial speed of the arrow, measured in meters per second.

\(t\) - Time, measured in seconds.

\(\theta\) - Launch angle, measured in sexagesimal degrees.

If we know that \(x_{o} = 0\,m\), \(v_{o} = 65\,\frac{m}{s}\), \(t = 0.85\,s\) and \(\theta = 25^{\circ}\), the horizontal distance between the archer and the tree is:

\(x = 0\,m + \left(65\,\frac{m}{s}\right)\cdot (0.85\,s)\cdot \cos 25^{\circ}\)

\(x = 50.074\,m\)

The distance between the archer and the tree is 50.074 meters.

11) The final speed of the banana (\(v\)), measured in meters per second, just before hitting the water is determined by the Pythagorean Theorem:

\(v = \sqrt{v_{x}^{2}+v_{y}^{2}}\) (Eq. 2)

Where:

\(v_{x}\) - Horizontal speed of the banana, measured in meters per second.

\(v_{y}\) - Vertical speed of the banana, measured in meters per second.

Each component of the speed are obtained by using these kinematic equations:

\(v_{x} = v_{o}\cdot \cos \theta\) (Eq. 3)

\(v_{y} = v_{o}\cdot \sin \theta +g\cdot t\) (Eq. 4)

Where \(g\) is the gravitational acceleration, measured in meters per square second.

If we know that \(v_{o} = 7.6\,\frac{m}{s}\), \(\theta = -40^{\circ}\), \(g = -9.807\,\frac{m}{s^{2}}\) and \(t = 0.75\,s\), the components of final speed are, respectively:

\(v_{x} = \left(7.6\,\frac{m}{s} \right)\cdot \cos (-40^{\circ})\)

\(v_{x} = 5.822\,\frac{m}{s}\)

\(v_{y} = \left(7.6\,\frac{m}{s}\right)\cdot \sin (-40^{\circ})+\left(-9.807\,\frac{m}{s^{2}} \right) \cdot (0.75\,s)\)

\(v_{y} = -12.240\,\frac{m}{s}\)

And the speed of the banana right before hitting the water is:

\(v = \sqrt{\left(5.822\,\frac{m}{s} \right)^{2}+\left(-12.240\,\frac{m}{s} \right)^{2}}\)

\(v \approx 13.554\,\frac{m}{s}\)

The speed of the banana when it hits the water is approximately 13.554 meters per second.

Explanation:

Yes, there are differences in the shapes of position-time graphs for uniform acceleration and uniform deceleration in different directions. Let's consider each case separately:\(\hrulefill\)

(1) - Uniform acceleration towards the positive direction:

In this case, the object is moving in the positive direction with a constant acceleration. The displacement-time graph will typically be a curve that starts from an initial position and shows a steady increase in displacement over time. The shape of the graph will depend on the specific acceleration value.

(2) - Uniform acceleration towards the negative direction:

In this case, the object is moving in the negative direction with a constant acceleration. The displacement-time graph will also be a curve, but it will show a steady decrease in displacement over time.

(3) - Uniform deceleration towards the positive direction:

In this case, the object is initially moving in the positive direction but is slowing down with a constant deceleration. The displacement-time graph will be a curve that starts with a positive slope and gradually levels off.

(4) - Uniform deceleration towards the negative direction:

In this case, the object is initially moving in the negative direction but is slowing down with a constant deceleration. The displacement-time graph will be a curve that starts with a negative slope and gradually levels off.

Answer:

Answer:

C) 128 kg*m/s

Explanation:

When you double something you multiply it by 2 most of the time. 64*2=128 or you can add it 64+64=128. Hope this helps.

(a) Object A has a decreasing speed during the time interval shown. This is because its velocity is decreasing (becoming less positive) over time, indicating a decrease in speed. Object B, on the other hand, has a constant speed during the time interval shown because its velocity is constant (zero) over time.

(b) Objects A and B are moving at the same speed at approximately t = 4 seconds and t = 8 seconds. This is because the velocity vs. time graph for object A intersects the velocity vs. time graph for object B at these times, indicating that their velocities are equal at these times. At all other times during the interval shown, the two objects are not moving at the same speed.

As per the given scenario, in this case, the coefficient of friction () is half and the coefficient of restitution (e) is zero.

Identify the body's starting velocity:

We may use the equation of motion to get the body's initial velocity (u)

\(v^2 = u^2 + 2as\)

\(0 = u^2 + 2(-9.8)m/s^2 * h\)

\(u^2 = 19.6h\)

u = √(19.6h)

The body's initial velocity (u) and initial relative velocity (u_rel) are the same.

The body's horizontal velocity immediately following the collision, which is zero, is the final relative velocity (v_rel).

\(e = v_{rel }/ u_{rel}\)

e = 0 / u_rel = 0 / u

Now, one can investigate the forces affecting the body: When a body is on an inclined plane.

There are two main forces at work on it: the frictional force that prevents the body from moving and the gravitational force that pulls it downward (mg).

The gravitational force has two components that act perpendicular to and parallel to the inclined plane, respectively: m*g*cos(45°) and m*g*sin(45°).

Determine the conditions for the body to stop:

μ * N = m * g * sin(45°)

μ * (m * g * cos(45°)) = m * g * sin(45°)

μ * cos(45°) = sin(45°)

(1/2) * cos(45°) = sin(45°)

Simplifying further, we have:

√2 / 4 = √2 / 2

Thus, the body will come to rest following the collision if the equation is valid.

Answer:

distance is not a vector. it is scalar

The motorcycle had covered a distance of 16 meters in half the total time.

a) To calculate the acceleration, we can use the formula:

a = (v - u) / t

where a is the acceleration, v is the final velocity, u is the initial velocity (which is 0 since the motorcycle starts from rest), and t is the time.

Given:

u = 0 m/s (initial velocity)

v = ? (final velocity)

t = 4 s (time)

s = 64 m (distance)

Using the equation of motion:

s = ut + 1/2at^2

We can rearrange the equation to solve for acceleration:

a = 2s / t^2

a = 2(64) / (4)^2

a = 128 / 16

a = 8 m/s^2

Therefore, the acceleration of the motorcycle is 8 m/s^2.

b) To find the final velocity, we can use the formula:

v = u + at

v = 0 + (8)(4)

v = 32 m/s

Therefore, the final velocity of the motorcycle is 32 m/s.

c) To determine the time at which the motorcycle had covered half the total distance, we divide the total distance by 2 and use the formula:

s = ut + 1/2at^2

32 = 0 + 1/2(8)t^2

16 = 4t^2

t^2 = 4

t = 2 s

Therefore, the motorcycle had covered half the total distance at 2 seconds.

d) To calculate the distance covered in half the total time, we use the formula:

s = ut + 1/2at^2

s = 0 + 1/2(8)(2)^2

s = 0 + 1/2(8)(4)

s = 0 + 16

s = 16 m
