Problem

Two blocks with masses

m_{1} = 4\,\text{kg}

and

m_{2} = 2\,\text{kg}

are connected by a light string passing over a pulley of mass

M = 4\,\text{kg}

and radius

R = 0.1\,\text{m}

. The pulley is a solid disk and rotates without friction. The system is released from rest. Calculate the kinetic energy of the pulley after the blocks have moved a distance of

1\,\text{m}
