Motion: Using the spring to roll a cart up a slope
Fit two large brackets (LB1) at the end of the track, one under the track and one upright using the 50 mm bolt (BLT2) and a wing nut (WN2).
Position the track at the 10 cm mark on the vertical pillar to give an angle of about 5˚.
Attach a spring to the cart.

Place the cart at the bottom of the track. Start logging and push the cart to compress the spring against bracket.
Release the cart and let the spring push the cart up the track. Let the cart run up the track and catch it as it returns.
Note: The suspended mass is only to tension the thread running over the pulley of the Rotary Motion sensor, it should only have a very minimal effect on the motion of the cart.
