A compact disc (CD) is known to have a constant angular acceleration of 40 rad/s^2. If it starts from rest, (a) what is its angular displacement after 10 seconds? (b) How many times does the CD have made complete revolutions?

A CD with a diameter of 12.0 cm starts from rest and with a constant angular acceleration of 1.00 rad/sec2 acquires an angular velocity of 5.00 rad/sec. The CD continues rotating at 5.00 rad/sec for 15.0 seconds and then slows to a stop in 12.0 second with a constant angular acceleration. What is the angular distance traveled by a point 4.00 cm from the center, at the time 10.0 seconds from the start?
