M 2M A block of mass M = 2.26 kg is at rest on a horizontal, frictionless surface. On one side a relaxed spring with a spring constant k = 169 N/m connects it to a wall; on the other side, a light string passing over a frictionless pulley connects it to another block, mass 2M, as shown. The pulley has a moment of inertia / = 4.9 x 10³ kg m² and a radius R = 0.053 m. A short time after the hanging block is released (from rest) it has fallen through a height of 0.091 m. At this point determine: a) the combined (total) kinetic energy of the blocks-and-pulley system J b) the rotational kinetic energy of the pulley. Krotal Krot = mJ
