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?

A ball is thrown vertically upward with a speed v from a height h above the ground . The time taken for the ball to hit the ground is

Two balls are thrown simultaneously, A vertically upwards with a speed of 20 m/s from the ground, and B vertically downwards from a height of 40 m with the same speed along the same line of motion. At what point do the two balls collide? Take g = 9.8 m//s^(2) .
