(b) The horizontal motion is simple, because a x = 0 a x = 0 and v x v x is a constant. Rearranging gives us: For the 1/3, 1/3, 1/3 profile, t a = t c = t d, and each segment equals 1/3 of the total time, t t. Thus, the equation becomes: And simplifying, we get: How to calculate maximum velocity. wikiHow is where trusted research and expert knowledge come together. Find the functional form of position versus time given the velocity function. Let's return to our drive to school, and look at a graph of position versus time as shown in Figure 2.15. Now, we know that velocity is maximum when y=0, i.e., displacement is zero and acceleration is zero, which means the system is in equilibrium. In a 100-m race, the winner is timed at 11.2 s.
