The 8-in. radius brake drum is attached to a larger flywheel that is not shown. The total mass moment of inertia of the drum and the flywheel is 15 lb.ft.s2 and the coefficient of kinetic friction between the drum and the brake shoe is 0.40. Knowing that the angular velocity of the flywheel is 450 rpm clockwise when a force P of magnitude 65 lbf. is applied to the pedal C, determine the number of the revolutions executed by the flywheel before it comes to rest. (The final answer should be in two decimal places with correct units)

Question
The 8-in. radius brake drum is attached to a larger flywheel that is not
shown. The total mass moment of inertia of the drum and the flywheel is
15 lb.ft.s2 and the coefficient of kinetic friction between the drum and
the brake shoe is 0.40. Knowing that the angular velocity of the flywheel
is 450 rpm clockwise when a force P of magnitude 65 lbf. is applied to
the pedal C, determine the number of the revolutions executed by the
flywheel before it comes to rest.
(The final answer should be in two decimal places with correct units)
