The flywheel of a steam engine runs with a constant angular speed of 475 rev/min. When steam is shut off, the friction of the bearings stops the wheel in 3.0 h.
(a) What is the constant angular acceleration, in revolutions
per minute-squared, of the wheel during the slowdown?
rev/min2
(b) How many rotations does the wheel make before stopping?
rotations
(c) At the instant the flywheel is turning at 75 rev/min, what is
the tangential component of the linear acceleration of a flywheel
particle that is 50 cm from the axis of rotation?
mm/s2
(d) What is the magnitude of the net linear acceleration of the
particle in (c)?
m/s2
