How many rotations does the wheel make before stopping

Reference no: EM13654485

The flywheel of a steam engine runs with a constant angular speedof 150 rev/min. When steam is shut off,the friction of the bearings stops the wheel in 2.7 h.

a) What is the constant angular acceleration,in revolutions per minute-squared, of the wheel during theslowdown?

b) How many rotations does the wheel make before stopping?

c) At the instant the flywheel is turning at 75 rev/min, what isthe tangential component of the linear acceleration of a flywheelparticle that is 50 cm from the axis of rotation?

d) What is the magnitude of the net linear acceleration of theparticle in (c)?
