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 2. QUESTION 2.1 Q3 Choose one . 11 points For the elastic collision you just preformed (Collision 2): Was momentum conserved? Yes O NoQUESTION 2.2 Q4 Choose one . 11 points For the elastic collision you preformed (collision 2): Was kinetic energy conserved? O Yes No GROUP 3 Collision 3 Group . 2 questions We will now examine a 3rd collision. Change the Elasticity slider in the box at the top right of the screen/sim to 09% (slid all the way to the left). Change the starting conditions to matching the image below.

Play around with different initial values that cause collisions at different angles and make some notes on scratch paper or on the data sheet. (if the balls hit the walls you results will be off)
