In working with the PASCO track and one dimension inelastic
collsions, we were calculating the percentage difference in the
before and after values of the collision's momenta.
We ran three different scenarios 0.5 + 0.5; 1.0 into 0.5, and
0.5 into 1.0 kg masses.  We consistently got the BEST results
with the 1.0 kg cart running into the 0.5 kg cart.  The equal
mass carts were the "worst" and the light cart into the heavier
cart was in the middle.
Any suggestions as to why this happened consistently.  We were
using the same two carts (added masses to increase value) all
of the time, and the same cart was the "incoming" cart which
did the colliding with the other one at rest.  I'm stumped.
Please give me some ideas if you have any.  Any reuminations on
the subject would be appreciated
