1.) Consider a head-on collision between two billiard balls of equal mass. The eight ball is initially at rest and the cue ball moves toward it, striking in a head-on collision. Velocity 8 The corresponding velocity vs. time graph for each ball should be: +x direction 0.36 0.34 0.32 Mass Cue Ball 268.2 g = Mass 8 Ball 285.6 g = 0.24 022 0.20 018 016 014 0.12 0.10 008 006 0.04 002 000 " 0.000 0.348 0.330 -0.006 0.0 02 04 0.6 08 10 12 16 1.450 1850 20 2.2 a.) Use the data above to determine if momentum is conserved. b.) Is the kinetic energy conserved? c.) Then what kind of collision was it? Does that make sense?
