A man A is sitting in the rear ens of a long compartment of a train running at constant horizontal velocity, tosses a coin to a person B, near the front end of the compartment. The trajectory of the coin is, as seen by B and a person C on the ground, will have:

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 ball is thrown from rear end to the front end of a compartment of a train which is moving at constant horizontal velocity. An observer sitting in the compartment and another observer standing on the ground draw the trajectory of the ball. They will have

In the figure the top view of a compartment of a train is shown. A man is sitting at a corner 'B' of the compartment . The man throws a ball ( with respect to himself ) along the surface of the floor towards the corner 'D' of the compartment of the train. The ball hits the corner 'A' of the compartment, then find the time at which it hits A after the ball is thrown . Assume no other collision during motion and floor is smooth. The length of the compartment is given 'l' and the train is moving with constant acceleration 'a' in the direction shown in the figure.
