A place kicker must kick a football from a point 36 m from the goal. As a result of the kick the ball must clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 24 m/s at an angle of 50o to the horizontal. The acceleration of gravity is 9.81 m/s2. Find its height with respect to the crossbar when it reaches the plane of the crossbar?
