2. Now let's add the second ball. Let's add another ball to the simulation. For this second ball, use the same velocity you used in 1(b) but change the mass

to half the mass of the basketball. Space the two balls apart so that there is a gap of~0.2 m between the centers as shown below (below, the basketball is the ball labeled '1' and in blue and both balls will be moving to the right initially). Be sure to write down which ball is which in the following tasks! а. Run the simulation using the "Slow" feature. Describe briefly how ball 1 and ball 2 are moving immediately before they collide for the first time. Note: you can use the buttons to either side of the "play" button to advance the simulation by 0.01 seconds. [2 pt] b. What are the velocities of ball 1 and 2 immediately before they first collide? [2 pt] с.What are the velocities of ball 1 and 2 immediately after they first collide? [2 pt] d. Calculate the total momentum of the system of ball 1 and ball 2 immediately before they first collide and immediately after they first collide. Is the total momentum conserved? If so, explain why. If not, explain why not. (Please show your calculations here!) [3 pt] e.Calculate the total kinetic energy of the system of ball 1 and ball 2 immediately before thy first collide and immediately after they first collide. Is the total mechanical energy conserved? If so,explain why. If not, explain why not. (Please show your calculations here!) [3 pt]
