The Trajectory of a Cannonball

The blue curve in the graph below shows the trajectory of a cannonball fired with a given muzzle velocity and angle of elevation (ignoring air resistance). The muzzle velocity is the speed of the cannonball when it leaves the cannon. The angle of elevation is the angle that the cannon is elevated above the horizontal. To change the trajectory, enter different values for the muzzle velocity and angle of elevation in the boxes below and click Plot trajectory.
The red markers show the trajectory of a cannonball fired with the same muzzle velocity at a 45 degree angle of elevation (the angle that gives the maximum range).
Muzzle velocity in feet per second:
Angle of elevation between 0 and 90 degrees:

Statistics for muzzle velocity 1700 ft./sec. and angle of elevation 55 degrees:
