Question

In the figure, two blocks, of masses 2.00 kg and 3 kg, are connected by a light string that passes over a frictionless pulley (i.e. the pulley is on a frictionless axle) of the moment of inertia 0.00400 kg · m^2 and radius 5.00 cm. However, there is sufficient friction between the pulley and the string such that the string turns the pulley without slipping (the string does not slip over the pulley). The coefficient of friction for the tabletop is 0.1 . The blocks are released from rest. Using energy methods, find the speed of the upper block just as it has moved 5 m. (answer in m/s)
