A CD player disk starts from rest and has a positive angular acceleration of $3\mathrm{.}50ra\frac{d}{s^2}($speeds up in the counterclockwise direction$),$ for $37\mathrm{.}0$ seconds. Then it continues rotating for $240$ radians at a constant angular velocity. Finally, after you are done listening to the song, the CD begins to slow down to a rest, which takes $36\mathrm{.}0$ seconds.

a$)$ How many radians did the CD spin in total?

$=$ rad.

b$)$ How many seconds did this all take?

$t=$ s$.$

c$)$ What was the average angular velocity?

${}_{\text{a}\text{v}\text{g}}=,ra\frac{d}{s}$

d$)$ How many revolutions did the CD spin?

$=,$ revolutions.
