The graph below shows h, the height i meters of a model rocket, versus t, the time in seconds after the rocket is launched. From the graph, what conclusion con be made about the flight of the rocket?

• The rocket reaches its maximum height after 2.5 seconds

• At 0 seconds the rocket was 2 meters off the ground

• The height of the rocket was 0 meters when it was launched

• The rocket was in flight for 5 seconds
