A student sets a top spinning clockwise at 218 rad/s. The top gradually slows down as it rotates through an angle of 827 rad before it comes to rest. Clockwise is defined as positive. Use radians as the standard unit for angles. What is the magnitude of the spinning top's angular acceleration?
The angular speed of a rotating platform changes from ω0 = 2.6 rad/s to ω = 8.8 rad/s at a constant rate as the platform moves through an angle Δθ = 4.5 radians. The platform has a radius of R = 44 cm. Calculate the angular acceleration of the platform α in rad/s2.

A large spherical gas cloud of radius = 5 x109 km has a mass = 2.4 x1030 kg, and is spinning to make one revolution in 60 years (i.e. Earth years, each of 365 days of 24 hours each). Due to gravity, the cloud gets smaller to a radius = 1.2 x106 km. What will be its period of rotation in minutes?
You are at a playground with a merry-go-round, which is initially sitting still. You push on it, causing it to accelerate in the angle at a rate of 1.2 rad/s2. If you push for 3 seconds How many radians will the merry-go-round have turned through during that time?
At t = 0s a grinding wheel has an angular velocity of 24.0 rad/s. It has a constant angular acceleration of 30.0 rad/s2 until a circuit breaker trips at t = 2.3 s. From then on it coasts to a stop over the next 10.0 seconds at constant angular acceleration. Through what total angle did the grinding wheel rotate? (Give your answer in radians.)
A computer hard disk starts from rest, then speeds up with an angular acceleration of 190 rad/s2 until it reaches its final angular speed of 7,200 rmp (revolutions per minute). How many revolutions has the disk made 10.0 s after it starts up? Do not enter units. Don't forget to convert rad/s to rev/s. A sketch of angular velocity versus time will help you solve this problem. Treat rev/s just as you would m/s.
