Question

The flywheel of a steam engine runs with a constant angular speed of 112 rev/ min . When steam is shut off, the friction of the bearings and the air brings the wheel to rest in 2.2 h. What is the magnitude of the constant angular acceleration of the wheel in rev/min22? Do not enter the units.

How many rotations does the wheel make before coming to rest?

What is the magnitude of the tangential component of the linear acceleration of a particle that is located at a distance of 40 cm from the axis of rotation when the flywheel is turning at 56.0 rev/ min?

What is the magnitude of the net linear acceleration of the particle in the above question?
