To win the game, a place kicker must kick a
football from a point 17 m (18.5912 yd) from
the goal, and the ball must clear the crossbar,
which is 3.05 m high. When kicked, the ball
leaves the ground with a speed of 15 m/s at
an angle of 58.9
from the horizontal.
The acceleration of gravity is 9.8 m/s
By how much vertical distance does the ball
clear the crossbar?
Answer in units of m
1) figure the time in air from
now knowing the time, figure the final vertical height.
now subtract the bar height.
