The tub of a washing machine goes into its spin cycle, starting from rest and gaining angular speed steadily for 9.00 s, at which time it is turning at 5.00 rev/s. At this point, the lid of the washing machine is opened, and a safety switch turns it off. The tub then smoothly slows to rest in 14.0 s. Through how many revolutions does the tub rotate while it is in motion? rev

A grinding wheel is in the form of a uniform solid disk of radius 7.06 cm and mass 2.02 kg. It starts from rest and accelerates uniformly under the action of the constant torque of 0.602 N-m that the motor exerts on the wheel. (a) How long does the wheel take to reach its final operating speed of 1180 rev/min? s (b) Through how many revolutions does it turn while accelerating? rev

A torque of 35.0 N⋅m is applied to an initially motionless wheel which rotates around a fixed axis. This torque is the result of a directed force combined with a friction force. As a result of the applied torque the angular speed of the wheel increases from 0 to 9.7 rad/s. After 5.90 s the directed force is removed, and the wheel comes to rest 61.0 s later. (a) What is the wheel's moment of inertia (in kg⋅m2)? kg⋅m2 (b) What is the magnitude of the torque caused by friction (in N⋅m)? N⋅m (c) From the time the directed force is initially applied, how many revolutions does the wheel go through? revolutions

A torque of 37.1 N⋅m is applied to an initially motionless wheel which rotates around a fixed axis. This torque is the result of a directed force combined with a friction force. As a result of the applied torque the angular speed of the wheel increases from 0 to 10.5 rad/s. After 5.80 s the directed force is removed, and the wheel comes to rest 61.0 s later. (a) What is the wheel's moment of inertia (in kg⋅m2 )? kg⋅m2 (b) What is the magnitude of the torque caused by friction (in N⋅m )? N⋅m (c) From the time the directed force is initially applied, how many revolutions does the wheel go through? revolutions
