Question 3
To win the game, a place kicker must kick a football from a point 25 m (27.34 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 17 m/s at an angle of 48.5 from the horizontal. The acceleration of gravity is 9.8 m/s2 .
By how much vertical distance does the ball clear the crossbar? Answer in units of m
