Problem 10.7

Please wait for the animation to completely load.

A turntable (a flat disk) of mass 5.0 kg is rotating at a constant speed when your finger makes contact with the outer edge, as shown in the animation (position is given in meters and time is given in seconds). Friction between your finger and the turntable causes the turntable to stop. What is the average torque on the turntable caused by the frictional force? Restart.
