A CD player disk starts from rest, and has a positive angular acceleration {it begins to spin quicker and quicker in the counter clockwise direction} of 3.9 radiansfsl for 45 seconds. Then, it stays at that angular velocity for 140 meters. Finally, after you are done listening to the song, the CD begins to slow to a rest, which takes 38 seconds. 1. Howr many radians did the CD spin total? 2. How many seconds did this all take? 3. What was the average angular velocity? 4. How many rotations did the CD spin
