At t=0 an object has a velocity of 35 m/s and a steady acceleration of -10 m/s2.   Make a sketch of velocity vs. time for this motion from t=0 to t=5 s. Make a sketch of acceleration vs. time for this motion from t=0 to t=5 s. Does the object change directions between 0 and 6 s?

Shown below is a graph of velocity-versus-time for a moving object. The object starts at position x = 0 m at t = 0 s. What is the final position at t = 4.0 s, in meters?

Starting at x = - 17 m at time t = 0 s, an object takes 17 s to travel 55 m in the +x direction at a constant velocity. On a sheet of paper, make a position vs. time graph of the object's motion. What is its velocity?

An airplane flies eastward and always accelerates at a constant rate. At one position along its path, it has a velocity of 34.9 m/s. It then flies a further distance of 44100 m, and afterwards, its velocity is 47.5 m/s. Find the airplane's acceleration. acceleration: m/s? Calculate how much time elapses while the airplane covers those 44100 m. elapsed time:

A particle moves accordingly to a law of motion s = f(t) = t^2 e^−t, t ≥ 0, where t is measured in seconds and s in feet. a. When is the particle speeding up? b. When is the particle slowing down?

A toy car can move to the right or left along a horizontal line (the positive portion of the distance axis). The positive direction is to the right. 0 + Choose the correct velocity-time graph (A - H) for each of the following questions. You may use a graph more than once or not at all. If you think that none is correct, answer choice J. A B D V e e 1 e + 0 0 0 e 0 1 0 Time Time Time Time E G H V 1 V + 0 e 0 1 0 0 None of these graphs is correct. Time Time Time Time Which velocity graph shows the car moving toward the left (toward the origin) at a steady (constant) velocity?

1. A stone is dropped from the top of a cliff. It is seen to hit the ground below after 4.5 seconds. How high is the cliff? 2. A ball is thrown vertically downward with a velocity of 20 m/s from the roof of a building that is 25 m high. How long does it take to hit the ground below? b. How fast was the ball going when it hit the ground? 3. A coin is tossed vertically upward and reaches a maximum height of 1.5 meters before it comes back down. What was its initial velocity? b. How long was it in the air? a. 4. A car rolls gently off a vertical cliff with an initial velocity of 0 m/s. How long does it take for the car to reach a speed of 75 km/hr? 5. The best rebounders in basketball have a vertical leap of about 125 cm. a. What is their initial launch speed off of the ground? b. How long are they in the air? 6. King Kong climbed the Bank of America Plaza in Atlanta which has a height of 312 m. a. How long did it take for him to fall? b. What was his velocity just before hitting the…

This is the velocity vs time graph. I would like to see how the position vs time graph will look like.

An apple falls from a tree. It hits the ground at a speed of about 5.0m/s5.0m/s. What is the approximate height of the tree?   10.0 m 2.4 m 2.5 m 1.3 m

At a stop light, a truck traveling at 15 m/s passes a car as it starts from rest. The truck travels at constant velocity and the car accelerates at 3 m/s2. How much time does the car take to catch up to the truck? Group of answer choices 10 s 25 s 15 s 20 s 5 s
