# Math Help - Hooke'sLaw

1. ## Hooke'sLaw

if a force of 12 N stretches a Hooke's law spring .20m beyond its natural length, how much work is done by the agent that does the stretching....
$F = kx$ ... use the given force and displacement to find the spring constant, $k$ , in Newtons/meter.
$W = \int_0^L kx \, dx$ , where $L$ = length the spring is stretched or compressed beyond its natural length
