A ball is thrown straight upward. Suppose that the height of the ball at time t is h = -16t^2 + 96t, where h is in feet and t is in seconds, with t = 0 corresponding to the instant the ball is first tossed.
A. How long does it take for the ball to land?
To do A, I must let h = 0 and solve for t, right?
B. At what time is the height 80 feet? Why does B have two answers?
To do B, I must let h = 80 and solve for t, right?
