A placekicker must kick a football from a point 36.0 m(about 40 yards) from the goal. Half the crowd hopes the ballwill clear the crossbar, which is 3.05 m high. When kicked, theball leaves the ground with a speed of 20.0 m/s at an angle of53.0° to the horizontal. (a) By how much does the ball clear orfall short of clearing the crossbar? (b) Does the ball approachthe crossbar while still rising or while falling?
