1. The problem statement, all variables and given/known data I was out for the lab we did a few weeks ago. What we did was measure the position and time data for a cart rolling down a ramp. Simple for everyone else, difficult for me because I wasn't there, plus I'm in about my first week of physics in school. This was the data my partner collected: time(sec) ... velocity (m/s) .15... .015 .40... .65 .65... .119 .85... .158 1.10... .212 1.3... .252 1.5... .285 1.75... .32 2. Relevant equations x = Ax^2 + Bx + C v = m(t) + b 3. The attempt at a solution My partner told me the position versus time equation is x = .1015t^2 - .065t + .0119, but I don't think that's right. I got v = (.188m/s)t - .002m/s, but I'm not sure if that's correct either.
