Rearranging an Algebraic Formula: Bass Curve

I have a formula, known as the Bass Curve Formula, that I would like rearranged. The formula generates an S curve that initially grows slowly, then accelerates before slowing down and plateauing. (See example) I would like the formula to be rearranged to find a variable (p). Please find the attached file for a detailed e ...continues

1) You shoot an arrow into the air, where it lands you probably do not care. However, let's just say that you do care for the brief moment in time that you work on this velocity problem. So, an arrow is shot straight up (vertically) into the air with a velocity of 157 ft/sec. Use the equation for motion under gravity and answer ...continues
