Angular Velocity and its Relation with Linear Velocity
Question

The tub of a washer goes into its spin cycle, starting from rest and gaining angular speed steadily for $$8.00\ s$$, at which time it is turning at $$5.00\ rev/s$$. At this point, the person doing the laundry opens the lid, and a safety switch turns off the washer. The tub smoothly slows to rest in $$12.0\ s$$. Through how many revolutions does the tub turn while it is in motion?

In a home laundry dryer, a cylindrical tub containing wet clothes is rotated steadily about a horizontal axis as shown in above figure. So that the clothes will dry uniformly, they are made to tumble. The rate of rotation of the smooth-walled tub is chosen so that a small piece of cloth will lose contact with the tub when the cloth is at an angle of $$\theta = 68.08$$ above the horizontal. If the radius of the tub is $$r = 0.330 m$$, what rate of revolution is needed?

A grinding wheel is in the form of a uniform solid disk of radius $$7.00\ cm$$ and mass $$2.00\ kg$$. It starts from rest and accelerates uniformly under the action of the constant torque of $$0.600\ N.m$$ that the motor exerts on the wheel. Through how many revolutions does it turn while accelerating ?
