Shooting down planes from the ground during WWII was difficult.A timed explosive is used because hitting a moving aircraft with asingle shot from a cannon is nearly impossible; This explosiveallows you to be less accurate. You are responsible for aiming andsetting the timed fuses for anti aircraft battery (cannon). Youfire a projectile that is aerodynamic enough that you can ignoreair resistance. The projectile leaves the barrel at 840m/s. Yourtarget is at an altitude of 3000m and a horizontal distance of4000m.
1.Find the flight time in algebraic expression.
2. At what angle above horizontal must you aim?
3.What does the delay need to be on the fuse?
