Problem: 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?

Newton's second law equation:

ΣF=ma

Tension in the cord:

T=mAmBgmA+mB

Mass mA rests on a smooth horizontal surface, mB hangs vertically.

T = (11.0)(7.0)(9.8)/(11.0 + 7.0) = 41.92 N

Problem Details

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?
