5. A wheel starts from rest and accelerates in such a way that its angular speed increases uniformly to 200 rpm in 60 s. After you have been spinning for some time at this speed the brakes are applied and the wheel takes 5 minutes to stop. If the total number of revolutions of the wheel is 3100, calculate the total time of rotation.

A student holds a bike wheel and starts it spinning with an initial angular speed of 7.0 rotations per second. The wheel is subject to some friction, so it gradually slows down. In the 10.0s period following the initial spin, the bike wheel undergoes 60.0 complete rotations. Assume the frictional torque remains constant, how much more time Δts will it take the bike wheel to come to a complete stop? The bike wheel has a mass of 0.625 kg and...

In the 10-s period following the inital spin, the bike wheel undergoes 60.0 complete rotations. Assuming the frictional torque remains constant, how much more time ?ts will it take the bike wheel to come to a complete stop? The bike wheel has a mass of 0.725 kg and...

A disk rotates about its central axis starting from rest and accelerates with constant angular acceleration. At one time it is rotating at 11.0 rev/s; 35.0 revolutions later, its angular speed is 21.0 rev/s. Calculate (a) the angular acceleration (rev/s2), (b) the time required to complete the 35.0 revolutions, (c) the time required to reach the 11.0 rev/s angular speed, and (d) the number of revolutions from rest until the time the disk reaches the 11.0 rev/s angular speed.
