A rocket is launched vertically upward from the ground with an initial velocity of 50 meters per second. The height h (in meters) of the rocket after t seconds is given by the function h(t) = -5t^2 + 50t. How long does it take for the rocket to reach its maximum height above the ground?
- 5 seconds
- 5 seconds (the rocket does not reach a maximum height because the coefficient of t^2 is negative)
- 10 seconds
- 50 seconds
