14) A projectile is fired from a cliff 300 feet above the water at an inclination of 45° to the horizontal, with a
muzzle velocity of 180 feet per second. The height h of the projectile above the water is given by
-32x2
h(x)
+ X + 300, where x is the horizontal distance of the projectile from the base of the cliff. Find
(180)
the maximum height of the projectile.
