A uniform disk of mass 401 kg and radius 0.20 m is mounted on frictionless bearings so it can rotate freely around a vertical axis through its center (see the following figure). A cord is wrapped around the rim of the disk and pulled with a force of 10 N. 10 N (a) How much work (in J) has the force done at the instant the disk has completed four revolutions, starting from rest? (b) Determine the torque due to the force. (Enter the magnitude in N · m.) N. m Calculate the work (in J) done by this torque at the instant the disk has completed four revolutions. (c) What is the angular velocity (in rad/s) at that instant? (Enter the magnitude.) rad/s (d) What is the power output (in W) of the force at that instant?
