Q. 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 $(h_{m})$ attained and the ranges (R) seen by the thrower and the outside observer compare each other?
Motion in a Plane
