SCENARIO 2: 100% Elastic collision between balls of unequal mass DIRECTIONS: STEP 1: Make sure the elasticity is still set at 100% and make the mass of the red ball double the mass of the green ball. Select an easy whole number velocity. 1. Predict what will happen after the red ball hits the green ball by scribbling out the wrong answer choices in each answer grouping (EX: slower/same(faster) After the collision, the red ball will move backwards/forwards at a speed that is slower/same/faster than its original speed. The green ball will move backwards/forwards at a speed that is slower/same/faster than the red ball's initial speed. 2. Run the simulation and see what happens. Were you right or wrong? O Right D Wrong STEP 2: Rerun the simulation. Fill in the data table below with the mass, velocity, and momentum BEFORE and AFTER the collision. Remember: the mass of the red ball should be double the mass of the green ball. Before Collision After Collision Velocity Momentum Velocity Momentum Ball Mass (kg ) (m/s) (kg *m /s) (m/s) (kg *m /s) 1 Total (Add Column values) What do you notice about the total momentum before and after the collision? Explain the change in velocity of the two balls after the collision. In other words, how does the velocity of the red ball after the collision compare to its velocity before the collision? How does the green ball's velocity after the collision compare to the red ball's velocity before the collision? How do the red ball and green ball's velocities after the collision compare with each other
