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
B. 37.5 rad
