1.Let's first just simulate the basketball being dropped (so ignoring the other balls). а. In the video, Dr. Dianna Cowern drops the basketball from about 1 meter above the ground.

Use kinematics or energy to estimate the velocity of the basketball when it reaches the ground. [2 pt] b. Assuming that the mass of a basketball is 0.5 kg, reduce the number of balls to 1 to simulate a single ball with this mass and half the velocity you found in (a) [the simulation doesn't allow fora greater velocity]. Select “more data" to input the velocity information. With the elasticity at 100% (completely elastic collision) and with the "Reflecting Border"selected, observe the simulated ball bounce off the right wall. In this collision, is the ball's momentum conserved? If so, why? If not, why not? Support your answer with screenshots of the simulation before and after the bounce. [2 pt]
