A place kicker must kick a football from a point 30.0 m (about 33 yd) 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 24.0 m/s at an angle of 57? to the horizontal. The acceleration of gravity is 9.81 m/s2 .
a) To determine if the ball clears the cross- bar, what is its height with respect to the crossbar when it reaches the plane of the crossbar?
