A block with mass ma 110kg on a smooth horizontal surface, Ask an Expert

Academics

A block with mass mA = 11.0kg on a smooth horizontal surface is connected by a thin cord that passes over a pulley to a second block with mass mB = 6.0kg which hangs vertically.

A) Determine the magnitude of the acceleration of the system.

B) If initially mA is at rest 1.250 mfrom 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 1100g?
