    A place-kicker must kick a football from a point 36.0 m?

    A place-kicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 20.6 m/s at an angle of 51.0? to the horizontal.
    (a) By how much does the ball clear or fall short (vertically) of clearing the crossbar? (Enter a negative answer if it falls short.)

    (b) Does the ball approach the crossbar (and cross above or beneath it) while still rising or while falling?
