| - | * Air density at Fenway park (sea level) is 1.196 kg/m^3. At one mile high in Denver, it's 0.986 kg/m^3. How much does the change in density affect the path of the ball at different angles and speeds? Try to change the above codes to find out. See if you can find a speed and angle that gives a home run in Denver but not at Fenway. | + | * Air density at Fenway park (sea level) is 1.196 kg/m^3. At one mile high in Denver, it's 0.986 kg/m^3. How much does the change in density affect the path of the ball at different angles and speeds? Try to change the above codes to show the path of the ball for both Fenway and Denver conditions. See if you can find a speed and angle that gives a home run in Denver but not at Fenway. |
| * Play around with the parameters in the functions, like the speed and angle of the ball. Can you figure out the minimum speed and optimal angle to just clear the outfiled fence and hit a home run? | * Play around with the parameters in the functions, like the speed and angle of the ball.
