Cannon ball projectile

This animation shows the trajectory of a cannon ball. You can use it to investigate the range at different barrel elevations and show that the range is greatest for an angle of elevation of 45o.

To fire the cannon press Start and press Reset to reload the cannon. Press Up or Down to change the elevation of the barrel and therefore the angle of projection of the cannon ball.
