P.s. Sorry…you made me geeky…but real men use slugs as units.

Equation x=0.5*a*t^2, if it is the equation you are talking about, is derived without calculus. It is just the area of right angle triangle with side “t” and and height “a*t” on the v —- t plane.

Here “a” is acceleration, so that during time “t” velocity goes from zero to “a*t”.
