The flywheel of a steam engine runs with a constant angular speed of 300 rev/min. When steam is shut off, the friction of the bearings stops the wheel in 2.2 hour.
(a) Find the constant angular acceleration, in revolutions per minute-squared, of the wheel during the slowdown?
rev/min2
(b) Find how many rotations does the wheel make before stopping?
rotations
(c) At the instant the flywheel is turning at 75 rev/min, find the tangential component of the linear acceleration of a flywheel particle that is 50 centimeter from the axis of rotation?
mm/s2
(d) Find the magnitude of the net linear acceleration of the particle in (c)?
m/s2
