2. In 2004, the highest spaceplane flight was made by Brian Binnie in SpaceShip One. A flight with this altitude (height) can be modeled by the function h(t)=-0.17+2+187t+61000, where h is the altitude (height) in meters and t is the flight in seconds. What was the height of the plane after 500 seconds? b. When did the plane land?​
