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:

Two balls are released simultaneously from a certain height, one is allowed to fall freely and other thrown with some horizontal velocity. How does the path of the balls appear to a person standing on the ground?

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.

Passenger of a train just drops a stone from it. The train was moving with constant velocity. What is path of the stone as observed by (a) the passenger itself, (b) a man standing on ground?
