The period T of a simple pendulum is the amount of time required for it to undergo one complete oscillation. If the length of the pendulum is L and the acceleration of gravity is g , then T is given by T = 2 π L p g q .

A force produces power p by doing work w in a time t. what power will be produced by a force that does six times as much work in half as much time?
