2. A toy rocket is launched from the ground and the arch can be modelled by the following equation, h = -0.4 (t - 7)² + 19, where h is the height, in metres, of how high the toy rocket is and t is the time, in seconds. a. What is the maximum height of the toy rocket? b. At what time did the rocket land after launching? c. At what time(s) is the toy rocket 5m from the ground?
