thank you for the help!:smile:

the direction will be "up",negative right?

mg(x+32)=1/2kx2 gives two answers but I can throw away the negative one, right? then I used F=-kx+mg => a= (-kx+mg)/m is that right?

you mean mg(x+32)=1/2kx2? should I then continue with F=-kx => F=ma solve out a?

should I use mgh=1/2kx2? x as how far it stretches from 32m? and then should I use F=-kx => F=ma and solve out a?

You go bungee jumping from a bridge that is 65m high, the bungee cord has an unstretched length of 32m and a spring constant of k=107 N/m You have a mass of 75kg. Question: what is the acceleration at the bottom, closest to the ground? I`ve tried to use 1/2kA2=1/2mx+1/2kx2 but it...
