Rotation: Angular Velocity Dynamics

Problem #: 2 | Variant #: 3

A 1.21 x 0.94 m rectangular piece of plywood is horizontally mounted in such a way that it can be spun about its center. There is a 0.1078 N-m torque while it is rotating due to friction in the bearings. If it is set spinning at a rate of 10 rpm and takes 10.8 s to come to a stop, what is the mass of the board?
