1.	Two perfecdy elastic balls of same mass m are movkng with velocities u_(1)and u_2. They collide elastically n times. The kinetic energy of the system finally is:
Answer» `1/2 m/n u_(1)^(2)` `1/2 m/n (u_(1)^(2) + u_(2)^(2))` `1/2 m(u_(1)^(2) + u_(2)^(2))` `1/2 MN(u_(1)^(2) + u_(2)^(2))` ANSWER :C
