Answer:

Explanation:

A ball is thrown in forward direction by a person who is riding on the roof of the moving train.

-->If you neglected the air drag and relative to the ground, then the velocity of the ball is equal to the sum of the velocities of ball and the train.

-->Hence, the ball is moving faster.

-(b) Relative to the freight car, the ball moves at the same speed irrespective of train
