The flywheel of a steam engine runs with a constant angular speed of 100 rev/min. When steam is shut off, the friction of the bearings stops the wheel in 1.1 h.
(a) What is the constant angular acceleration, in revolutions per minute-squared, of the wheel during the slowdown?
(b) How many rotations do the wheel make before stopping?
(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?
(d) What is the magnitude of the net linear acceleration of the particle in (c)?
