one-dimensional movement exercise:
Two balls are dropped in a vacuum from the same height, but at
different times; The second ball hits the ground 1.35 seconds after
the first hits the ground.
A. from the above information, deduce an expression that allows you
to find the difference between your heights (∆h = h2-h1)

A rock is dropped from a height of 110 meters above the ground. One second later, a ball is thrown vertically downward from the same height with an initial speed of 14 m/s. A. At what time after the ball if thrown are the two objects at the same height above the ground? B. What is the speed of the rock when the ball hits the ground?
A ball is dropped from rest at a height h. Directly below on the ground, a second ball is simultaneously t thrown upwards with a speed of vc. The two balls collide at the moment that the second ball is instantaneously at rest. (They collide when the second ball is at its maximum height.) What is the height of the collision? At what time does the collision occur if both balls' motion stated at t = 0 s?
1. Two metal balls (A and B) are the same size, but ball A has a mass of 20 kg and ball B has a mass of 10 kg. Ball A is dropped from a height of 100 meters above the Earth in a vacuum (so that we can ignore air resistance). 1 second later Ball B is dropped from the same location. While they both are falling, which has a greater gravitational force acting on it? Explain.
(1 point) A ball is dropped from a height of 10 feet and bounces. Suppose that each bounce is 5/8 of the height of the bounce before. Thus, after the ball hits the floor for the first time, it rises to a height of 10 ) = 6.25 feet, etc. (Assume g = 32ft/s and no air resistance.) A. Find an expression for the height, in feet, to which the ball rises after it hits the floor for the nth...
A 1 kg ball and a 10 kg ball are dropped from a height of 10 m at the same time. In the absence of air resistance, O the 10 kg ball will take 10 times the amount of time to reach the ground. O the two balls will hit the ground at the same time. 0 there is not enough information to determine which ball will hit the ground first. O the 10 kg ball will hit the ground...
(3 points) A ball is dropped from a height of 14 feet and bounces. Suppose that each bounce is 6/8 of the height of the bounce before. Thus, after the ball hits the floor for the first time, it rises to a height of 14 ) = 8.75 feet, etc. (Assume no air resistance.) A. Find an expression for the height, in feet, to which the ball rises after it hits the floor for the nth time: hm = 14(5/8^n...

2. A ball is dropped from the top of a 20 m building at the same time that another ball is thrown upward from a height of 2 m above the ground. If the two balls pass on an other at the height of 10 m, determine the speed at which the second ball was thrown upward Answer | 12.6 m/s.
A ball is dropped from a height 24 m above the ground at t=0.0. Each time it bounces from the ground, its rebound speed is 60% of its impact speed. At the instant the first ball hits the ground, a second ball is released from the same place. Take g = 9.8 m/s2. At what height above the ground will they collide? (Take the ground as y=0.0 m)
