The angular velocity of a flywheel obeys the equation $\omega_{z}(t)=A+B t^{2},$ where $t$ is in seconds and $A$ and $B$ are constants having numerical values 2.75 (for $A$ ) and 1.50 (for $B$ ). (a) What are the units of $A$ and $B$ if $\omega_{z}$ is in $\mathrm{rad} / \mathrm{s} ?$ (b) What is the angular acceleration of the wheel at (i) $t=0$ and (ii) $t=5.00 \mathrm{~s} ?$ (c) Through what angle does the flywheel turn during the first 2.00 s? (Hint: See Section $2.6 .)$
