A boy in a open trucj throws a ball at `40 m//s` at angle `60^(@)` form horizontal. The truck is moving with constant speed `10 m//s` and the boy just after throw, jumps off the truck and starts running in same direction to catch the ball. (Assume same horizontal level)

A truck starts from origin, accelerating with a m s^-2 in positive x - axis direction. After 2 s , a man standing at the starting point of the truck projected a ball at an angle 30^@ with velocity v m s^-1 . Find the relation between a and v such that the ball hits the truck. (Assume that truck is moving on horizontal plane and the man projected the ball from the same horizontal level of truck).

A boy throws a ball with a velocity of 15 m/s at an angle of 15° with the horizontal. The distance at which the ball strikes the ground is

The coach throws a baseball to a player with an initial speed of 20 m//s at an angle of 45^@ with the horizontal. At the moment the ball is thrown, the player is 50 m from the coach. At what speed and in what direction must the player run to catch the ball at the same height at which it was released? (g = 10 m//s^2) .

A boy sitting at the rear end of a railway compartment of a train, running at a constant acceleration on horizontal rails throws towards the fore end of the compartment with a muzzle velocity of 20m/sec at an angle 37^(@) above the horizontal, when the train is running at a speed of 10 m/sec. If the same boy catches the ball without moving from his seat and at the same height of projection,find the speed of the train at the instant of his catching the ball.

A train is moving along a straight line with a constant acceleration 'a' . A boy standing in the train throws a ball forward with a speed of 10 m//s , at an angle of 60(@) to the horizontal. The boy has to move forward by 1.15 m inside the train to catch the ball back at the initial height . the acceleration of the train , in m//s^(2) , is
