A second ball is dropped down from an elevator acceleration up with `1 m//s^(2)`, 1 second after the first ball is dropped. How does the relative velocity of the two balls change with time. How the ratio `v_(1)//v_(2)` change with time.

A ball A is dropped from a building of height 45 m . Simultaneously another ball B is thrown up with a speed 40 m//s . Calculate the relative speed of the balls as a function of time.

Two steel balls fall freely on an elastic slab. The first ball is dropped from a height h_(1) and the second from a height h_(2)(h_(2) lt h_(1)) sec after the first ball. After the passage of time T, the velocities of the balls coincide in magnitude and direction. Determine the time T and the time interval during which the velocities of the two balls will be equal assuming that the balls do not collide.

A ball is dropped downwards . After 1 second another ball is dropped downwards from the same point . What is the distance between them after 3 seconds .

A ball A is dropped from the top of a tower 500m high and at the same instant another ball b is projected upwards with the velocity of 100m/s. after how much time and where the two balls will meet?

A lift is moving with uniform downward acceleration of 2 m//s^(2) . A ball is dropped from a height 2 metre from the floor of lift. Find the time after which ball will strike the floor.

A ball is dropped from a bridge at a height of 176.4 m over a river. After 2s, a second ball is thrown straight downwards. What should be the initial velocity of the second ball so that both hit the water simultaneously?
