...holy shades of Isaac Newton, Batman ;) What you want to know is position (distance, D) at a given time, T. Youll plug distance into your trans value, assuming youre accelerating in a straight line from a standing start: Frame # = 20 * T A = Acceleration = (96.54/3) = 32.18 meters per second squared T = Time D = distance = (AT/2)(T) = 16.08TT For example: At time 1.5 seconds your distance (xtrans, or whatever axis youre using) = 16.081.51.5 = 36.18 Frame # = 20*1.5 = 30
