Question
A person sitting in the rear end of a 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 height (hm) attained and the ranges (R) seen by the thrower and the outside observer compare each other?

Solution
The correct option is A Same hm, different R
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, hm will be same, but R will be different.
