The height
of an object dropped from a hot-air balloon can be determined by the
formula h = —16t2 + s,
where h is the height of the object in feet, t is
the elapsed time in seconds, and s is the height of the
balloon. If the balloon is 400 feet from the ground, how long will it take for an object dropped from the balloon to hit the ground? |
