1) Determine the extension of the trampoline when a 200 kg person stands on the trampoline. (k=12000)

2) If on the first push, the trampoline went 8.0 cm below its position in part 1, find the average force exerted by his leg muscles?

For the first question i was able to get 0.33m (i think that's the answer, i used mgx=1/2kx^2)

but i have no idea how to do the second question...
