A counterweight of mass m = 4.00 kg is attached to a light cord that is wound around a pulley as in Figure PI 1.18. The pulley is a thin hoop of radius R = 8.00 cm and mass M = 2.00 kg. The spokes have negligible mass, (a) What is the magnitude of the net torque on the system about the axle of the pulley? (b) When the counterweight has a speed v, the pulley has an angular speed a) = v/R. Determine the magnitude of the total angular momentum of the system about the axle of the pulley, (c) Using your result from part (b) and? = dL/dt, calculate the acceleration of the counterweight.
