A piece of wood is pressed against a spindle sanding disk which is a uniform disk with a radius of 0.090 m, rotating at an initial angular velocity of 37.0 rad/s (ωi = 37.0 rad/s). This motion results in a constant tangential frictional force of magnitude f = 9.00 N and causes the sanding disk to come to a complete stop in = 25.0 s. 1. What is the torque on the sanding disk due to the force exerted by the wood; no additional torques act other than the one caused by the wood. 2. What is the mass of the sanding disk, assuming it is a uniform disk. 3. During the first 7.0 s of sanding, what is the change in rotational kinetic energy of the disk.
