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