On a separate sheet on binder paper, please answer the question and turn it in to me at the beginning of the next class.

A paper airplane follows a parabolic path with , where h is the height in meters, and t is the time in seconds. Algebraically determine how long it takes for the paper airplane to hit the ground. Then algebraically determine the maximum height the paper airplane will reach. (Show all work!)
