URGENT!!! DUE IN 30 MINS!! if a 40 kg weight and a 200 kg weight are each dropped from 1 m above the trampoline, find the final position of each weight. Assume the trampoline is a simple spring obeying Hooke's law with a k value of 12 000 N/m. I was able to get the answer to the part of this, using mg(h+x) = 1/2kx^2 but i got a negative and a positive answer, which one do i choose? (i got 0.29 and -0.22)
