We have a rod-shaped space station of length 687m and mass 5.35 x 10^6 kg, which can change its length (kind of like an old-fashioned telescope), without changing its overall mass. Suppose that the station is initially rotating at a constant rate of 2.26 rpm. If the length of the rod is reduced to 2.26m, what will be the new rotation rate of the space station? 4.38 rpm 7.50 rpm 3.50 rpm 6.25 rpm

You have a horizontal grindstone (a disk) that is 88 kg, has a 0.31 m radius, is turning at 89 rpm (in the positive direction), and you press a steel axe against the edge with a force of 17 N in the radial direction. Assuming that the kinetic coefficient of friction between steel and stone is 0.20, calculate the angular acceleration of the grindstone in rad/s2. What is the number of turns, N, that the stone will make before coming to rest?
A crankshaft rotating at 10.2 rad/s undergoes an angular acceleration of 2.2 rad/s^2. What is the angular velocity of the shaft after 11.0 s? Give your answer in rad/s.
A ferris wheel begins at rest. During the first part of the journey, the ferris wheel accelerates through 4 rotations at a rate of 0.0500 rad/s2. During the second part of the journey, the ferris wheel then remains at its top speed for 14 rotations. Finally, during the third part of the journey, the ferris wheel slows down to rest over 3 rotations. What is the ferris wheel's top angular speed? How long does it take for the ferris wheel to accelerate from rest up to its top speed? How long the ferris wheel remain at its top speed for? How long does it take for the ferris wheel to slow down from top speed to rest?
