A block with mass m1 hangs from a rope that is extended over an ideal pulley and attached to a second block with mass m2 that sits on a ledge slanted at an angle of 20° (see figure below). Suppose the system of blocks is initially held motionless and, when released, begins to accelerate.  If  m1 = 7.25 kg,   m2 = 2.25 kg,  and the magnitude of the acceleration of the blocks is 0.150 m/s2, find the magnitude of the kinetic frictional force between the second block and the ledge. What is the value of the coefficient of kinetic friction between the block and the ledge?
