The flywheel of a steam engine runs with a constant angular speed of 165 rev/min.
When steam is shut off, the friction of the bearings and of the air brings the wheel to
rest in 2.30 hrs
(a) What is the constant angular acceleration of the wheel, in rev/min2 ?
(b) How many rotations will the wheel make before coming to rest?
(c) What is the tangential linear acceleration of a point 54.2 cm from the axis of
rotation when the flywheel is turning at 75.2 rev/min
(d) What is the magnitude of the total linear acceleration of the point in part (c)?

I will be happy to critique your work.
