 A ball is bouncing elastically with a speed of $1 \mathrm{m}/\mathrm{s}$ between walls of a railway compartment of size $10 \mathrm{m}$ in the direction perpendicular to walls. The train is moving at a constant speed of $10 \mathrm{m}/\mathrm{s}$ parallel to the direction of motion of the ball as seen from the ground.
