The flywheel of a steam engine runs with a constant angular speed of 350 rev/min. When steam is shut off, the friction of the bearings stops the wheel in 2.7 hour.

(a) Find the constant angular acceleration, in revolutions per minute-squared, of the wheel during the slow down?

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 fly wheel 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
