2. A large number of identical elastic balls are moving randomly inside a fixed vertical cylindrical container under a piston that is at a height h = 1.0 m above the bottom of the container. The container is kept inside a gravity free chamber. Root mean square speed of the balls is of the order of 102 m/s and mean collision time of the balls is of the order of 10 s. The piston is suddenly made to move upwards with a constant velocity u = 1.0 m/s and stopped at a height 2h above the bottom of the container. Find ratio of total internal energy of the balls in the new steady state to that of initial state. %3D
