A uniform disk with a mass of 120 kg and a radius of 1.4 m rotates initially

Question:

A uniform disk with a mass of 120 kg and a radius of 1.4 m rotates initially with an angular speed of 1100 rev/min.

(a) A constant tangential force is applied at a radial distance of 0.6 m. What work must this force do to stop the wheel?

(b) If the wheel is brought to rest in 2.5 min, what torque does the force produce? What is the magnitude of the force?
