When an old LP turntable was revolving at $33 \frac { 1 } { 3 } \mathrm { rpm }$ it was shut off and uniformly
slowed down and stopped in 5.5 seconds.
(a) What was the magnitude of its angular acceleration $\left( \text { in } \mathrm { rad } / \mathrm { s } ^ { 2 } \right)$
as it slowed down?
(b) Through how many revolutions did it turn while stopping?
