Question Part Points Submissions Used 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 22.0 m/s at an angle of 52.0° to the horizontal. By how much does the ball clear or fall short (vertically) of clearing the crossbar? (Enter a negative answer if it falls short.)

Explanation / Answer

The time to travel 36 m is given by
t = 36 / 20 cos 52 = 2.923 s.

In this time it travels a vertical height given by
h = 20 sin 53*2.991
