Okay, I finally got it! A2*K/vmax2 = m = 0.9609 = 0.961kg Thank you Swatje, dirk_mec1, and lukas86, thank you very much! Off to more studying, but I will most likely be back soon :) Thanks again!

D'oh. Okay, well I've taken that into consideration and am now getting 0.922~. I thought there was something wrong with that, but I don't see what I should have done... i should multiply by m? :confused:

Okay, so I see that I didn't square A... but when I do, I am left with the answer 0.4147...

Ok a. vmax = A*SQUR(k/m) b. vmax2 = A * (k/m)2 (now out of the square root) c. vmax2/A = k/m2 (divided by A) d. vmax2/(Ak2) = m2 (divided by k, unsure if it should be squared or not) e. SQUR(vmax2/(AK2)) = m (not sure if this is necessary)

Tried numerous times, getting things such as: m = vmax2/A(k)2 m = SQUR(vmax2/A(k)2) m = vmax2/Ak m = vmax/A(k)2 etc. But I'm still not getting it. :frown: I have a physics exam tomorrow and am practicing so that I can actually pass, and this question for whatever reason or other is...

Okay, while this does help and I feel I am on the verge of getting it right, i still didn't get it. I am left with equations such as m=vmax squared divide by A*K and variations of those variables being squared. Thanks for your patience, though, I realize I am very out of my league with physics.

a) Yes, when attempting I made sure that A was 0.817kg. b) I don't really understand what you are saying... I can try to explain the formula I expect I need to use better: Vmax = A√k/m That symbol being the square root, of course. The reason I mentioned "squaring" some things is...
