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 velocity of $20 m / s$ .A person standing outside on the ground also observes the ball.How will the maximum heights $y_{m}$ attained and the ranges $R$ seen by the thrower and the outside observer compare with each other?
same $y_{m}$ and $R$
same $y_{m}$ different $R$
differently $y_{m}$ same $R$
differently $y_{m}$ and $R$

The motion of train will affect only the horizontal component of the velocity of the ball-Since - vertical component is same for both observers- the ym will be same -but range R will be different-

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