A counterweight of mass m = 3.60 kg is attached to a light cord that is wound around a pulley as shown in the figure below. The pulley is a thin hoop of radius R = 7.00 cm and mass M = 1.50 kg. The spokes have negligible mass. M 111 (a) What is the net torque on the system about the axle of the pulley? magnitude N.m direction --Select--- (b) When the counterweight has a speed v, the pulley has an angular speed = v/R. Determine the magnitude of the total angular momentum of the system about the axle of the pulley. kg.m)v (c) Find the magnitude of the acceleration of the counterweight. m/s²
