Question 1188328: a toy rocket is launched upward from ground level with an initial velocity of 51 meters per second. It’s height is a function of time, given h = -4.9t^2 + 51t, where h represents the height in meters and r represents the time in seconds. What is the maximum height reached by the rocket and how long is it in flight?
