I guess it could be. What I wrote is the exact wording of the question but I don't think it was a very good question.

I agree with what you’re saying, which is why I was so confused about the question. I think I’ll include that reasoning in my solution along with my calculation of the escape velocity of the sun. Thanks!

So if I pick a point within the Sun's gravitational field, then I could use that r and the mass of the Sun?

So you mean there is no answer?

I'm pretty confused by this but I have a few thoughts. Since the sun takes up most of the mass of the solar system, I was thinking maybe I'm really looking for the escape velocity of the sun? So I would use the mass of the sun for M and the radius of the sun for r. My other thought was to add up...

Oh ok, that makes sense! Thanks again for your help, I really appreciate it.

I’m a bit confused on how to do that since there’s a few variables I don’t know. I would use m=4, g=9.8, h1=52, v1=0, k=20, x1=0 (I think), and h2=0. But then I don’t know v2 or x2.

Great thanks for all your help!

Oh I see. So I calculated the speed just when the bungee begins to stretch as 29.4m/s. Then I used conservation of energy as mgh1 + 1/2mv1^2 = 1/2kx2^2. I used h1=x2 and v1=29.4m/s, and got x2=15.3m. 15.3+44.1 is 59.4, so the box would still hit the ground but the answer is more reasonable. Does...

Oh ok. So this is the diagram I was using, should I have no x1?

Do you mean the 44.1m doesn’t count as initial compression because the bungee was slack?

This is more of a check that I solved this assignment correctly. I got to an answer but I’m not sure it’s correct. First, I decided that I needed to solve for the maximum stretch of the bungee. To do that I think I needed the length of the bungee (which is also the initial compression). So...
