A stone is dropped from the top of a tower 50 m high. Simultaneously another stone is thrown upwards from the ground with a speed of 20 "m.s"^(-1) . Calculate the time at which both the stone cross each other.

A boy playing on the roof of a 10 m high building throws a ball with a speed of 10 m//s^(-1) at an angle of 30^(@) with the horizontal. How far from the throwing point will the ball be at a height of 10 m from the ground?

A ball is projected horizontally with a velocity of 5ms^(-1) from the top of a building 19.6 m high. How long will the ball take to hit the ground ?

A boy standing on a stationary lift (open from above) throws a ball upwards with the maximum initial speed he can equal to 49 ms-1. How much time does the ball take to return to his hands ? If the lift starts moving up with a uniform speed of 5 ms^(-1) and the boy again throws the ball up with the maximum speed he can, how long goes the ball take to return to his hands ?
