Energy is extracted from a flywheel with an initial rotational frequency of f 0 in such a way that the frequency decreases linearly with time. Describe the power output as a function of time as the flywheel slows. a. The power output decreases linearly with time. b. The power output decreases as the square of the elapsed time. c. The power output increases linearly with time. d. The power output increases as the cube of the elapsed time. e. The power output increases as the square of elapsed time
