Question: A rotating flywheel slows down with constant angular acceleration due to friction in its bearings. At t = 0, its angular velocity is 420 rad/s.

A rotating flywheel slows down with constant angular acceleration due to friction in its bearings. At t = 0, its angular velocity is 420 rad/s. At t = 60 s, its angular velocity is 340 rad/s.

(a) What is the angular velocity at t = 180 s?

(b) Through how many revolutions has it turned at t = 180 s?
