Mass mA rests on a smooth horizontal surface, mB hangs vertically.
(a) If mA=11.0 kg and mB=7.0 kg, determine the magnitude of the acceleration of each block.
(b) If initially mA is at rest 1.300 m from the edge of the table, how long does it take to reach the edge of the table if the system is allowed to move freely?
(c) If mB=1.0 kg, how large must mA be if the acceleration of the system is to be kept at over 1/100 g?
