a constant angular acceleration of $30\mathrm{.}0$ rad$>$s

$2$

until a circuit breaker

trips at t $=2\mathrm{.}00$ s$.$ From then on$,$ it turns through $432$ rad as it coasts to

a stop at constant angular acceleration. $($a$)$ Through what total angle did

the wheel turn between t $=0$ and the time it stopped? $($b$)$ At what time

did it stop? $($c$)$ What was its acceleration as it slowed down?
