A flywheel is a solid disk that rotates about an axis that is perpendicular to the disk at its center. Rotating flywheels provide a means for storing energy in the form of rotational kinetic energy and are being considered as a possible alternative to batteries in electric cars. The gasoline burned in a 144-mile trip in a typical midsize car produces about 1.05 x 109 J of energy. How fast would a 18.7-kg flywheel with a radius of 0.247 m have to rotate to store this much energy? Give your answer in rev/min.

A solid disk (moment of inertia = 20 [kg⋅m2][kg⋅m2]) rotates around an axle (with friction) connected to a device capable of reading the total energy at any given point in time. At point 1 the total energy is 250 [J] and point 2 the total energy is 160 [J]. If the speeds at point 1 and point 2 are 3 [rad/s] and 4 [rad/s], respectively, how much work is done by the non-conservative forces in this system?
