47. [-/5 Points] DETAILS OSUNIPHYS1 10.8.P.100. A uniform disk of mass 411 kg and radius 0.26 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 two revolutions, starting from rest? J (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 two 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? W MY NOTES PRACTICI
