A flywheel, that has most of its mass at its rim, can rotate about an axis that is perpendicular to the wheel at its center. Rotating flywheel provide a means for storing energy in the form of rotational kinetic energy, and are being used in some electric power plant to store excess electrical energy. How fast would a M= 14-kg flywheel with radius R = 0.35 m, have to rotate (that is, what should be its in rad/s), to store . × of rotational kinetic energy? (Rotational Inertia of a flywheel is I = MR2

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
