Question

A crane winch is lifting a 2300-kg mass. The winch can be modeled as a cable of negligible mass wound around a solid uniform cylinder with a 12-cm radius and a mass of 320 kg that rotates around its central axis. How much torque is required to accelerate the 2300-kg mass straight upward at 0.35 m>s2? Assume there is no friction in the system and that the winch radius remains constant.
