A cannon is fired from Fort George towards Fort Niagara during the War of 1812. Fort George is on a 100 meters cliff above level ground. The launch speed of the canon is 100m/s at an angle of 20 degrees. Assuming no air resistance. Determine: 1. how long the cannon ball will be in the air? 2. the peak height of the canon ball. 3. if the ball will clear the Fort Niagara wall of 10 m (the wall is 850 m away from the base of the cliff) 4. the range with no wall to possibly impede the canon ball
