I used a bobbing Cenco spring. Got good results at low stretch and high
velocity (PE + KE = total). But all other areas it bombs out.
I tried a Pasco 2.2 m tract with a cart and a spring on each side of the
cart attached to an end stop. Too much friction.
Now I am using the Pasco Air Tract with a glider attached to two springs
(one on each end). Lots better but have not yet done the caculations.
