As shown in the figure, a 1.8 kg cylinder can rotate about an axle (yellow). R=16 cm; L=67.2 cm.

(a) Calculate its moment of inertia about its center.

kg·m2

(b) When there's no torque applied, it slows down from 1800 rpm to rest in 57.0 s. Now we want to make it come to rest from 1200 rpm in 4.00 s by applying a constant torque on it. What is the minimum torque applied?
