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 .

I can measure the magnitude of the force from the fan by turning it on and letting it push up against a force probe. With this, it seems to push with a force of about 0.2 Newtons (your fan may vary).
