Answer
The correct answer is:
C. Equal
Work Step by Step
Let the magnitude of the work done initially by the pads be $F~d$. We can find the magnitude of the work done by the pads in the second workout:
$Work = (\frac{F}{2})~(2d) = F~d$
Since the magnitude of the work done by the pads is equal to the energy dissipated, the two values are equal.
The correct answer is:
C. Equal
