We will now examine a 4th collision. Make sure the blue slider on the right side of the simulation is all the way to the left. It should be set to 0% elastic or inelastic. Change the starting conditions to matching the image below. Ball 1: 2kg Position -1 Velocity 1. Ball 2: 2kg Position 1 Velocity -1 Based on the initial conditions, calculate the momentum and kinetic energy of both balls, along with their total, and add that information to the "before" columns of the data sheet collision 4. Click "Play" to run the simulation and pause it after they collide. Based on the new values of velocity of each ball, calculate the momentum and kinetic energy of both balls, along with their total, and add that information to the "After" columns of the data sheet collision 4
