WebSep 9, 2024 · In a physics equation, given a constant acceleration and the change in velocity of an object, you can figure out both the time involved and the distance traveled. For instance, imagine you’re a drag racer. Your acceleration is 26.6 meters per second 2, and your final speed is 146.3 meters per second. Now find the total distance traveled. WebAt some time t, when you pass the Porsche, these x values will be the same. So, we can set the equations equal to one another and solve for time, and then plug the time back in to either x equation to get the distance from the stop line. Doing this gives: -15 + 11.11 t = 1.5 t 2. Bringing everything to one side gives: 1.5 t 2 - 11.11 t + 15 = 0
