Experiment 2A - Sticking (Elasticity 0%) . Click "Reset All" . In the box on the right side of the screen, select the following settings: velocity vectors ON, reflecting borders OFF, momenta diagram ON, elasticity 0%. Click on "More Data" and fill in the information below. Be sure to include units. Then click "Restart." Before: Mass of red ball: Mass of green ball: Velocity of red ball: Velocity of green ball: Momentum of red ball: Momentum of green ball: Momentum of System Before Collision (Pred + Pgreen) = Click play, and then fill in the information below for After: Mass of red ball: Mass of green ball: Velocity of red ball: Velocity of green ball: Momentum of red ball: Momentum of green ball: Momentum of System After Collision (Pred + Pgreen) 1. What happens to the momentum of the red ball after the collision? a. Increases, but stays in the same direction b. Increases, and changes direction c. Decreases, but stays in the same direction d. Decreases, and changes direction 2. What happens to the momentum of the green ball after the collision? a. Increases, but stays in the same direction b. Increases, and changes direction C. Decreases, but stays in the same direction d. Decreases, and changes direction 3. What happens to the total momentum of balls after the collision? a. Increases b. Decreases c. Stays the same 4. The ball that changed direction after the collision had a. A larger initial momentum b. a smaller initial momentum
