1. The problem statement, all variables and given/known data I'm studying for my MCAT and currently on translational motion. Rather than memorize the formulas, which would be useless for this type of test, I'm trying to learn and understand where the formulas come from, which requires knowing how to derive them. I need help with deriving the following translational motion equation: 2. Relevant equations vx2 = vo2 + 2axΔx 3. The attempt at a solution This equation is used for solving Physics problems in which time is not relevant. I tried substituting equivalent expressions for time (e.g. Δv/a and Δx/v) into other translational motion equations, but it was no use. =( I'm wondering if it's a Calculus based derivation? Or perhaps I am over thinking this and it's a common sense formula that has no derivation? Please help!
