Kinectic energy and power.
One way to store energy is in the rotational motion of a flywheel, and some have proposed using such technology to power automobiles. One unit is based on a 6.5-kg flywheel in the shape of a hoop of radius 5.0x10-2 m that spins as fast as 50000 rpm PartA How much kinetic energy is stored by the flywheel when it is rotating at its maximum rate? Express your answer to two significant figures and include appropriate...
