## The Trajectory of a Cannonball

The graph below shows two possible trajectories for a cannonball. The dotted red line shows the trajectory when the angle of elevation of the cannon (the angle
it is raised above the horizontal) is 45 degrees. The blue line shows the trajectory for a different angle of elevation, which you can specify in the box next to **Angle of
elevation** below.

To change the trajectories, enter different values for the angle of elevation and muzzle velocity below and
click **Plot trajectories**.
