Question

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

Answer 1

In vertical direction, ball has zero initial velocity but same value of g w.r.t observer A & B,so they will draw trajectory of equal vertical range

But along horizontal direction, for observer A, ball is moving with velocity at which it is thrown w.r.t. train while for B, it is moving with a velocity equal to train + velocity at which it is thrown w.r.t groundtrain

Answer 2

Answer:

vertical range is equal but horizontal range is different........

Explanation:

In vertical direction, ball has zero initial velocity but same value of g w.r.t observer  A & B,so they will draw trajectory of equal vertical range

But along horizontal direction, for observer A, ball is moving with velocity at which it is thrown w.r.t. train while for B, it is moving with a velocity equal to train + velocity at which it is thrown w.r.t groundtrain
