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

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
