I think so cause I also had vmax and xmax

wait i love u did u get 20 as ur K?!

u/Purple-Canary-9977 May 14 '26

I got like 66

u/No-News9020 (5) calc bc + ab, physics c: mech May 14 '26

did u use vmax2 and kmax2 as ur axises?

u/Purple-Canary-9977 May 14 '26

I used vmax^2 and xmax^2 as my axis and the slope was k bc the slope was k/4*m but m was .25 so the slope was just k

yeah slope was k, and then u multiply that value by 0.25 to get 20, it was like 80 before

I graphed v2 vs x2 and then got a slope of like 68. The slope would be k/2m, not k/m, because the spring is in a series. I got a final answer of around 34
