I JUST NEED ANSWER Mass mA rests on a smooth horizontal surface, mB hangs vertically. a) If mA =15.0 kg and mB =3.0 kg in the figure (Figure 1), determine the magnitude of the acceleration of each block. b) If initially mA is at rest 1.200 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 [tex]\frac{1}{100}[/tex] g?
