To win the game, a place kicker must kick a football from a point 19 m from the goal, and the ball must clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 16 m/s at an angle of 59.8 from the horizontal. The acceleration of gravity is 9.8 m/s. By how much vertical distance does the ball clear the crossbar?
