The mass of the disk is 0.35 kg with a radius of 0.18 m and is initially spinning at 5 revolutions per second. It is spinning horizontally and on a very low friction axle. Then a uniform thin rod of length 0.40m and mass of 0.085 kg is suspended just above the spinning disk and dropped, without any rotational motion, onto the spinning disk exactly across its diameter. After the rod is dropped, the rod and disk are moving with...

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 424-mile trip in a typical midsize car produces about 2.31 x 109 J of energy. How fast would a 28.4-kg flywheel with a radius of 0.396 m...
