Question

Here is a different function modeling the height of a

potato, in feet, seconds after being fired from a different
device:
-161? + 80t +64
How could you determine the time at which the potato
hits the ground? You do not need to determine the
answer. Just explain HOW you would go about
doing so.

Answer 1

An object is thrown straight up from the top of a building h feet tall with an initial velocity of v feet per second. The height of the object as a function of time can be modeled by the function h(t) = –16t2 + vt + h, where h(t) is the height of the object (in feet) t seconds after it is thrown.

Explanation:

A ball is thrown straight up from the top of a 128 foot tall building with an initial speed of 32 feet per second. The height of the ball as a function of time can be modeled by the function h(t) = –16t2 + 32t + 128. How long will it take for the ball to hit the ground?
