In US football, after a touchdown the team has the opportunity to earn a point by kicking the ball over a bar between two posts. The bar is 3.05m tall and 10.97m horizontal from the location where the ball is being kicked. If the ball is kicked at 45 degrees above the horizontal, what must its initial speed be if it is to just clear the bar. Express the answer in m/s and km/hr.
