2. For Christmas, I received a paint ball gun that fires each round with a muzzle velocity of 100
feet per second. In order to work on my aim, I use my husband as target practice. So as to
avoid retaliation, I cannot aim directly at him. I must fire the gun at an inclination of 45
degrees to the horizontal. This gives me time to hide behind the grill on the back deck. The
following equation models the height (h) of the paint ball in terms of the horizontal distance
(x) that the paint ball travels from my firing point on the deck.
h(x) =
-32x²/100² + x + 10
