For motion with constant velocity the average velocity equals the instantaneous velocity. It is important to note that in this case the displacement is equal to the area under the velocity–time curve. But is this true of any velocity–time graph? It is but to prove this we must use integr...
Having a strictly uniform velocity at a given time frame makes the velocity at that time frame equal to the average velocity.Answer and Explanation: We are given a ball with an initial velocity of 10 m/s for 2 seconds. In this case, we could assume that the...
For the coin, find (a) the maximum height reached, (b) its position and velocity 4.00 s after being released, and (c) the time before it hits the ground.A soft tennis ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.10 m. (...
A ball is thrown horizontally at a speed of 6.52 m/s off of a 10.11m tall cliff. How much time will it take to reach the bottom of the cliff? How can you tell from a velocity-time graph that you are accelerating in the negative dire...
Question: After 3.0 h, an object's displacement is 2.60 x 10^2 km north. What is the average velocity of the object? Average Velocity: If we want to find the average velocity of an object, we need to divide the displacement of that object by the...
A ball is dropped from a height of 50 meters. Find the impact velocity and the time it takes to hit the ground. Why do all free falling objects have the same acceleration? The rate of change in an object's velocity is the object's w...
