Question: A clockwise variable torque is applied to a flywheel at time (t=0) causing its clockwise angular acceleration to decrease linearly with angular displacement (theta) during

A clockwise variable torque is applied to a flywheel at time $t=0$ causing its clockwise angular acceleration to decrease linearly with angular displacement $\theta$ during 20 revolutions of the wheel as shown. If the clockwise speed of the flywheel was $300 \mathrm{rev} / \mathrm{min}$ at $t=0$, determine its speed $N$ after turning the 20 revolutions. (Suggestion: Use units of revolutions instead of radians.)
