Question

A person sitting in the compartment of a train moving with uniform speed throws a ball in the upward direction. What path of the ball will appear to him? What to a person standing outside the train?

Answer 1

The person who is sitting inside the train,

he or she will observe the vertical motion only

because the object and the person are both moving

with same velocity in horizontal direction.

For the person outside the train path would be parabolic in nature.

Because the person is outside the train but still but

the object have constant horizontal velocity and

varying vertical velocity.
