A person sitting in the rear end of the compartment throws a ball towards the front end. The ball follows a parabolic path. The train is moving with uniform velocity of $$20$$ $$ms-1$$. A person standing outside on the ground also observes the ball. How will the maximum heights (hm) attained and the ranges (R) seen by the thrower and the outside observer compare each other?

Question

A person sitting in the rear end of the compartment throws a ball towards the front end. The ball follows a parabolic path. The train is moving with uniform velocity of $$20$$ $$ms-1$$. A person standing outside on the ground also observes the ball. How will the maximum heights (hm) attained and the ranges (R) seen by the thrower and the outside observer compare each other?

Infinity Learn · Accepted Answer

The motion of the train will affect only the horizontal component of the velocity of the ball. Since, vertical component is same for both observers, the hm will be same, but R will be different.
