[J87/11/9] A body A of mass m moving with velocity u makes an elastic head-on collision with an identical body B which is initially at rest. (a) Describe in words the motion of the bodies after the collision. (b) The elastic collision mentioned above is one in which the bodies become temporarily compressed and remain in contact for a short time. On the same axes of velocity against time, sketch labelled graphs of velocity of A and the velocity of B. The time axis should extend from a time before the bodies come into contact to a time after they separate; mark on this axis the time to at which they first touch, the time to at which they suffer maximum compression and the time ts at which they separate. (c) Explain why bodies have the same velccity at to (the time of maximum compression).
