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 deceleration. What is the angular distance traveled by a point 4.00 cm from the center, at the time 10.0 seconds from the start?

A. 27.6 rad B. 37.5 rad C. 40.7 rad D. 48.2 rad E. 51.2 rad
