|A baseball is hit upward with an initial velocity of
= 80 feet per second (or about 55 miles per hour) and leaves the bat with
an initial height of =
a). Write a formula s(t) that models the height of the baseball after t seconds.
a. If the initial velocity of an object is feet per second and its initial height is feet, then the height, in feet, of the object after t seconds can be modeled by the equation .
Now is given to be 80 and is given to be 3. Substituting these values into function s gives .
