A football is kicked from the ground for a field goal with a resultant velocity

Question

A football is kicked from the ground for a field goal with a resultant velocity of 22 m/s at an angle of 40° from the horizontal. Determine the following:

1. How long is the ball in the air?

2. How high does the ball go?

3. How far does the ball go?

4. If the ball is kicked from the 40-yard line, will it go over the crossbar?

5. Keeping the angle constant, how do your answers change if the velocity is increased by 10%? Decreased by 10%?

6. Keeping the velocity constant, how do your answers change if the angle is increased by 10%? Decreased by 10%?

Explanation / Answer

X = 22*cos40*2.88
