Need physics help with Uniform disks and rotation

/in /by

A uniform disk with a mass of 145 kg and a radius of 1.4 m rotates initially with an angular speed of 1180 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? 
 ________kJ

(b) If the wheel is brought to rest in 2.5 min, what is the magnitude of the torque produced by the force? 
______________ N · m 
What is the magnitude of the force? 
_____________ N 

(c) How many revolutions does the wheel make in these 2.5 min? 
_____________ rev
