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 m/s. 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
