Question

A projectile is fired vertically upward from a height of

175

175

feet above the ground, with an initial velocity of

1800

1800

ft/sec. Recall that projectiles are modeled by the function

h(t)=−16t2+v0t+y0

. Write a quadratic equation to model the projectile's height

h(t)

h(t)

in feet above the ground after t seconds.

Step 1

Consider the given data.

Step 2

The height h of a projectile above the ground after t seconds is given by

Step 3

Therefore, the projectile...
