M,R A pulley with radius R and moment of inertia about its central axis 1/2 MR is mounted on frictionless bearing. A massless cord is wrapped around the pulley with mass m attached on one side and massless spring with spring constant k on another side. The spring is connected to the ground. Cord does not slip on the pulley. Find acceleration of the box at the point at which the spring is maximally stretched (at this point the block instantaneously stops). т
