Question

In a figure, 

m1 = 10.4 kg

 and 

m2 = 4.3 kg.

 The coefficient of static friction between m1 and the horizontal surface is 0.50, and the coefficient of kinetic friction is 0.30.

An illustration shows a rectangular block of mass m1 on the horizontal surface of a table. This is connected to another rectangular block of mass m2 by a cord that runs over a pulley placed diagonally at the corner of the horizontal surface of the table. The rectangular block of mass m2 is suspended vertically by the side of the tabletop.
(a) If the system is released from rest, what will its acceleration be? (Enter the magnitude of the acceleration.)
 m/s2

(b) If the system is set in motion with m2 moving downward, what will be the acceleration of the system? (Enter the magnitude of the acceleration.)
 m/s2
