Ball A is thrown up vertically with speed 10 m/s . At the same instant another ball B is released from rest at height h . At time t , the speed of A relative to B is

A ball A is thrown up vertically with a speed u and at the same instant another ball B is released from a height h . At time t , the speed A relative to B is

A ball is thrown vartically upward with speed 70 m//s . After 1 s, another ball is dropped from a height 185 m in the same vertical line. When and where the balls collide?

A ball is thrown vertically upward with speed 40 m//s . Simultaneously, another ball is dropped from a height 200 m in the same verticle line. When and where the balls meet?

A ball is thrown upwards with a speed of 20m/s from the ground. Another ball is dropped from rest from a building 80m high at the same time (i) Find the difference in their height after they have fallen for 2s? (ii) If the balls are along the same line of motion, when will they colide?

From the top of a toward of height 60 m , a ball is thrown vertically upward with speed 20 m//s . After some time, the ball strikes the ground. Sketch the v-t and s-t graph.

A ball 'A' is thrown upwards from ground level with a velocity of 20 ms^(-1) . Another ball 'B' is thrown downwards from a height of 40 m with the same speed. Find the height at which the two balls meet (take g = 10 m s^(-2) ).

A ball is thrown vertically upwards with a speed of 10 m//s from the top of a tower 200 m height and another is thrown vertically downwards with the same speed simultaneously. The time difference between them on reaching the ground is (g=10 m//s^(2))

A ball is thrown up at a speed of 4.0 m/s. Find the maximum height reached by the ball. Take g=10 m//s^2 .

A body is dropped from a height h=50 m. Another body is projected vertically up with a speed V=10 m//sec after a time t_0 = 2 sec from the instant of release of the first body. Find the time of their meetings.
