A body throws a ball from shoulder height at an initial velocity of 30 m/s. Spending 4.8 s in air, the ball is caught by another boy as the same shoulder-height level. What is the angle of projection ?

A boy throws a ball vertically upward with an initial speed of 15.0m//s .The ball was released when it was at 2.00 m above ground. The boy catches it at the same point as the point of projection (a) What is maximum height reaches by the ball ? How long is the ball in the air?

A cricket ball thrown across a field is at heights h_1 and h_2 from the point of projection at times t_1 and t_2 respectively after the throw. The ball is caught by a fielder at the same height as that of projection. The time of flight of the ball in this journey is
