Asked by Bami
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)?
