(a) If mA = 13.0 kg and mB
= 5.0 kg in Fig. 4-45, determine the acceleration of each block. (b) If
initially mA is at rest 1.250 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 g?
