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?

Constants| Periodic Table Part A In the figure the lower disk, of mass 430 g and radius 3.1 cm, is rotating at 180 rpm on a frictionless shaft of negligible radius. The upper disk, of mass 270 g and radius 2.5 cm, is initially not rotating. It drops freely down onto the lower disk, and frictional forces bring the two disks to a common rotational speed. (Figure 1) Find the final common frequency in rpm. Express your answer using two...
