x=Asin(wt) w=1.4832 x=-7 A=7 m=77 k=169.4 -7=7sin(1.483t) -1=sin(1.483t) arcsin(-1)=1.483t t=1.059=1.06-->I think I have found the answer that my professor is looking for! Let me know if this is not correct, otherwise, Thank you all so much!

Ahh, that is what i suspected... If you had to take a guess what would you say the correct answer is given the answer choices?

Here it is word for word from the hw. You (all brave 77 kg of you) have volunteered to jump from a bridge while attached to a bungee cord. You fall 22 m from rest, beginning at time t = 0.0 s, before the cord begins to stretch. The cord stretches 14 m before you begin to move back upward. As...

I suspect the cycle repeats itself in the same oscillating motion it was before.

Yes I am using T=2π√m/k and I get 4.2361 as the time for one period. divide it by 2 and i get 2.11. Well that is already bigger than the answer choices so I don't think adding more time to it would help...

So am I on the right track? I really have no idea how to finish off this hw, and will likely need a definitive answer.

Yes. The person jumping is 77 kgs. Sorry about that.

I have a love for physics and am from italy. I play soccer, and love helping with physics. So I hope i can be of help here.
