Find the angle through which the cd has rotated

Reference no: EM13539816

At the start of a CD it is spinning at a rate of 569 rpm (revolutions per minute). Just as the CD finishes playing it is spinning at a rate of 247 rpm. While playing, the CD undergoes a constant angular acceleration of -8.29·10-3 rad/s2.

a) Find the angle through which the CD has rotated during its playing time.

b) Find the playing time.
