8. Physics students were modeling the height of a ball once it was dropped from the roof of a 25 story building. The students found that the height in feet, h, of the ball above the ground as a function of the number of seconds, 1, since it was dropped was given by h(t)= 300–16r² . From what height was the ball dropped? To the nearest tenth of a second, determine the time at which the ball hits the ground. Provide evidence from a table to support your answer or solve this algebraically if you recall how to.
