A mаss = [m] kg is tied tо а rоpe thаt is wrapped arоund a pulley and connected to a spring with spring constant . The rope and pulley are essentially massless and frictionless. At the initial position of the system (illustrated by top block), the spring is at equilibrium length. When the block has dropped a distance = [d] m, the system is again at rest. What is the value of the spring constant ? Please give your answer in units of N/m.
