4.What angle can you kick a football that will the make the initial vertical component of the velocity equal to the initial horizontal

component of the velocity?  ____

5. Name an angle that you could kick a football that would give it a very large initial vertical component but a small nonzero initial

horizontal component. _____

6. How would the vertical component of a velocity change if the angle of projection was changed from 80 degrees to 60

degrees? _____
