Oh and this as well:

To stretch a spring a distance x_1 from its unstretched length, an amount of work of W must be done.

How much work must be done to compress this spring a distance x_2 from its unstretched length?

power is work/time

that should be a pretty good hint

You need to know either:Oh and this as well:

To stretch a spring a distance x_1 from its unstretched length, an amount of work of W must be done.

How much work must be done to compress this spring a distance x_2 from its unstretched length?

that the formula for work done in either compressing or stretching a spring a distance x is (1/2)kx

(what follows immediately from that formula)

that the work done in compressing or stretching a spring a distance x is proportional to x

IF W is the work done stretching the spring a distance x_1 and W_2 is the work done in compressing it a distance x_2, then

W/(x_1)

W_2= (x_2/x_1)
