Homework Help: college physics

A particular grinding wheel is a uniform solid disk of radius 8cm and mass 3kg. While the wheel is spinning at 50rad/s. A tool is pressed against its rim in a way that causes a friction force of 40N. If the disk is just "coasting" when the torque is applied, at what rate will its angular velocity start to decrease?
