A football is kicked by a football player. It's initial trajectory is at an angle of ø = 50° above the horizon and has a speed of u = 45 m s-1. The ball lands away from the initial position at a location 7.5m higher from where it was originally kicked. If air resistance is neglected and gravity is taken to be 9.8 m s-2, what is the balls time of flight and therefore prove that it is 6.8 seconds.
