    Find the Trajectory's Launch Angle

    Homework Statement A cannon fires at a hilltop target with a muzzle velocity of V = 600 ft/s. The horizontal and vertical distances to the target are L = 0.5 miles and h = 0.25 miles. Determine the elevation angle at which the cannon should be fired. L=2640 ft h=1320 ft...
