NOTES
Aim the motion sensor so that it can see the cart along the entire track, except for the 0.5 m blind spot directly in front of the sensor.
The acceleration vs time graph may be too noisy to be useful, in which case use the slope of the best-fit line to the relevant portion of a velocity vs time graph.
Use the "Motion and Force" experiment file with the calibration info for the particular force sensor. Zero the force sensor (using the software) when it is secured to the cart with no force on the hook.
