Two objext A and B are moving along the same line. At the time t=0, B is 75ft ahead of A. The acceleration of A is 1.8ft/s^2 and the acceleration of B is -1.3ft/s^2. The velocity of A is 32ft/s and the velocity of B is 51ft/s.
Find (a) when and the distance that A catches up with B and (b) the velocity of A and the velcoity of B at that time.
