At t $=0,$ a flywheel has an angular velocity of $9\mathrm{.}7$ rad$/$s$,$ an angular acceleration of $-0\mathrm{.}45$ rad$/$s$,$ and a reference line at $0$o $=$ O$.($a$)$ Through what maximum angle max will the reference line turn in the positive direction? What are the $($b$)$ first and $($c$)$ second times the reference line will be at $0=0$max$/7?$ At what $($d$)$ negative time and $($e$)$ positive time will the reference line be at $=-9\mathrm{.}5$ rad?
