n Review Constants Part A A flywheel in a motor is spinning at 580 rpm when a power failure suddenly occurs. The flywheel has mass 40.0 kg and diameter 75.0 cm. The power is off for 37.0 s, and during this time the flywheel slows down uniformly due to friction in its axle bearings.

A flywheel (a uniform solid cylinder of radius 0.25 m and mass 80 kg) is initially at rest, but free to rotate about the axis through its center. A belt wrapped around it is pulled off horizontally, providing a tangential force of 45 N to the outer rim of the flywheel for 2.00 s. Calculate the final kinetic energy of the wheel.

1.A solid uniform sphere of mass 3.7 kg and radius 0.051 m rotates with angular velocity 7.3 rad/s about an axis through its center. Find the sphere’s rotational kinetic energy. 2.A certain pulley is a uniform disk of mass 2.7 kg and radius 0.25 m. A rope applies a constant torque to the pulley, which is free to rotate without friction, resulting in an angular acceleration of 0.12 rad/s2. The pulley starts at rest at time t = 0 s....
