A projectile is fired from a cliff 200 feet above the water at an incline of 45°to the horizontal, with a muzzle velocity of 50 feet per second. The height h of the projectile above the water is modeled by
h(x)=(-32x^2)/〖50〗^2 +x+200

@LEAH99,
The formula is h(t) = h0 + v0 t + 1/2 a t^2 where

ho is the initial height
v0 in the initial vertical velocity = 50 * sin(45)
a is the acceleration due to gravity = -32 ft/sec^2
t is time

Plugging in what you provided,

h(t) = 200 + 50 (sin 45) t - (1/2) 32 t^2
