Two blocks with masses m1 = 1.10 kg and m2 = 3.10 kg are connected by a massless string, as shown in the Figure (the figure shows m1 on top of a box and m2 hanging off the side of the box). They are released from rest. The coefficent of kinetic friction between the upper block and the surface is 0.320.
Assume that the pulley has a negligible mass and is frictionless, and calculate the speed of the blocks after they have moved a distance 44.0 cm.
