1. Since we varied both initial velocity and mass: does it appear that conservation of momentum and conservation of energy hold across all trials regardless of initial conditions? You can look at indi'tidual trials, sets of trials with similar conditions: as well as the means across all elastic trials. Eire there any patterns? For example; did higher mass or faster velocities do a better job of shot-ring momentum or kinetic energy conservation? If soJ 1th? might this he?
