Set the launch speed to 25 [m/s] and the launch angle to 30. Without clearing the run, set the launch angle to 60and run a second trial, so that both curves are simultaneously visible. What do you notice? Is this a coincidence, or part of a broader principle? Explain.

1. Continuing from the prior question, keep the launch speed fixed, but adjust the launch angle to try to optimize the horizontal range. What angle serves this purpose best? Does it match your expectations? Is this the same as the "best" angle to punt a football in a game?What other considerations might apply in that case?
