Determine how much work do you do

Reference no: EM13501985

A wheel is mounted on a stationary axle, which is nearly frictionless so that the wheel turns freely. The wheel has an inner ring with mass 5 kg and radius 10 cm and an outer ring with mass 2 kg and radius 25 cm; the spokes have negligible mass. A string with negligible mass is wrapped around the outer ring and you pull on it, increasing the rotational speed of the wheel. During the time that wheel's rotation changes from 4 revolutions per second to 7 revolutions per second, how much work do you do?
