Homework Help: physics

Posted by anonymous on Tuesday, December 11, 2007 at 8:47pm.

Two blocks of mass m1 = 1.2 kg and m2 = 1.7 kg are connected by a massless string, as shown in the Figure. They are released from rest. The coefficent of kinetic friction between the upper block and the surface is 0.45. Calculate the speed of the blocks after they have moved a distance 26 cm. Assume that the pulley is massless and frictionless.
