A CD with a diameter of 12.0 cm starts from rest and with aconstant angular acceleration of 1.00 rad/sec2 acquires an angularvelocity of 5.00 rad/sec. The CD continues rotating at 5.00 rad/secfor 15.0 seconds and then slows to a stop in 12.0 seconds with aconstant angular deceleration. What is the angular distancetraveled by a point 4.00 cm from the center at the time 25.0seconds from the start?
A. 107 rad
B. 193 rad
C. 205 rad
D. 237 rad
E. 274 rad
