A placekicker must kick a football from a point 36.0 m (about39.0 yd) fm the goal, and the ball must clear the crossbar, whichis 3.05 m high. When kicked the ball leaves the ground with avelocity of 22.0 m/s at an angle of 46.0 to the horizontal.

(a) By how much does the ball clear or fall short clearing thecrossbar?

(b) Does the ball approach the cross bar while still rising orwhile falling?
