Physics

A block with mass mA = 15.0 kg on a smooth horizontal surface isconnected by a thin cord that passes over a pulley to a secondblock with mass mB = 6.0 kg which hangs vertically.
Determine the magnitude of the acceleration of the system.
Express your answer to two significant figures and include theappropriate units.
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 systemis allowed to move freely?
Express your answer to two significant figures and include theappropriate units.
If mB = 1.0 kg, how large must mA be if the acceleration of thesystem is to be kept at g100?
Express your answer to two significant figures and include theappropriate units.
