According tolegend, in 1589, the Italian scientist Galileo Galileidropped rocks of different weights from the top ofthe Leaning Tower of Pisa to prove his conjecturethat the rocks would hit the ground at the same time. The height h (in feet) of a rock after t seconds can bemodeled by h(t) = 196 − 16t^2. Find and interpret the zeros of the function. Then use the zeros to sketch the graph.
