Question: A large solid spool, with mass 60 kg and radius 50 cm, is wrapped with a long piece of lightweight rope. This rope is attached to the axle of an electric motor that can deliver 1.5 W of power. When turned on, the motor winds the rope onto the motor axle causing the large spool to rotate.

Part A: After the motor is switched on, how long will it take the large spool to reach a rotation speed of 30 revolutions per minute (i.e., rpm)?

Please show all work and steps I am really trying to learn this for my exam.
