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 23.9 m/s at an angle of 51.5 degrees to the horizontal.

In step 4 substituting the valves into the equation for the, y- component of the displacement above gives the following result. Remember that ay--g.
y=0+ ( ) m/s) ( ) s) 1/2( m/s^2) ( )s^2) = ( ) m
Given:-
A place-kicker must kick a football from a point of 36.0 m from the goal.
Half the crowd hopes the ball will clear the crossbar, which is high h = 3.05 m.
the ball leaves the ground with a speed of 23.9 m/s at an angle of 51.5 degrees to the horizontal.
