The flywheel of a steam engine runs with a constant angular speed of a 149 rev/min. When the steam is cut off, the friction of the bearings and of the air brings the wheel to rest in 1.9 hours. a) assuming it is constant, what is the angular acceleration of the wheel? b) how many rotations will the wheel make before coming to rest? c) what is the tangential linear acceleration of the particle 49 cm from axis of rotation when the flywheel when it is turning at 74 rev/min? d) what is the magnitude of the total linear acceleration of the particle in the Part C? Can someone Please help me on this question, and walk me through the steps.
