Need physics help with Uniform disks and rotation
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
