in feet above the ground after t seconds.

Step-by-step explanation:

It is given that, a projectile is fired vertically upward from a height of 300  feet above the ground, with an initial velocity of 900 ft/s.

The general equation with which a projectile are modled by the function is given by :

y₀ is the initial height above the ground

v₀ = initial velocity

So,

This is the quadratic equation that models the projectile height in feet above the ground after t seconds.
