NO cases make both velocities not zero. In the third case, choose initial velocities so A and B are :site directions and collide head on. In the fourth case, choose initial velocities so A and B are moving ection. (Note that the kinetic energy ratio in the last two cases depend on the initial velocities, not only M agreement between the nal velocity in the simulation and the formula in the 6th column. This momentum conservation with the assumption that the nal speeds of A and B are equal. Table 1: Completely inelastic collisions astic collision (Total kinetic energy before and after collision stays the same.) mary target Iation. Set the "Elasticity" to "100%" (\"Elastic"). Try the following cases in the simulations and fill out In the first case, choose Ivfl''lllB , choose MB> M)d1 for the second case, and MA: MB for Your simulation data should show agreement between the nal velocity VAf in the simulation and the 6* column, as well as the nal velocity va in the simulation and the formula in the last column. 3 come from combining momentum conservation and kinetic energy conservation.
