Falling Object Model ( When an object with little air resistance is dropped, its speed will continually increase) h = -16t2 + s h the height (in feet) of such an object when done falling sthe height(in feet) from which the object was dropped tthe # of seconds in which it has fallen

3
Example h = -16t2+s A swimmer drops a towel from a 10 foot diving board. How many seconds will it take to hit the pool deck?

4
Example A ball is dropped from a 300 foot building. How many seconds will it take to hit the ground?
