The cart then detects motion over these lines to give position-time data. Again using the quadratic fit I can find the acceleration. In this case it gives a value of 0.1092 m/s 2 .

The velocity time graphs give all three variables for motion–velocity which can be read off at any time. Area is displacement and gradient is acceleration. Next page.

Since the starting velocity is zero m/s and the starting position is zero meters, this is pretty easy. After a time interval of 5.12 seconds, the car should have traveled 126.9 meters with an ...
