The rooftop of a 5-story building is 50 feet above the ground.
How long does it take the water balloon dropped from the
rooftop to pass by a third-story window at 24 feet?
Using the model h(t) = h, 16², solve the equation
h(t) = 24. (When you reach the step at which you divide
both sides by -16, leave 16 in the denominator rather than
simplifying the fraction because you'll get a rational
denominator when you later use the quotient property.)
