Go to Phet and find collision lab or type in Name http://phet.colorado.edu/sims/collision ... ab_en.html Set up your page so it looks like this Momenta p™mv PP₁P₂ Reset All LIN UM Have 1 Dimension selected, velocity vectors, center of mass, and momentum diagram. Elasticity is set at 1.00 On the bottom, select "More Data", this will give mass, as well as velocity and momentum values. Collision 1: Same Mass Predict, with the current set up, AFTER collision -what will each object's velocity and momentum be prior to and after collision (use formulas if needed!)
