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 1.6 radians per second squared, for 36 seconds. Then, it stays at that angular velocity for 300 radians. Finally, after you are done listening to the song, the CD begins to slow to a rest, which takes 25 seconds. Please round all answers to the nearest whole number.
1. How 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 ?
