The trajectory of an object that is thrown from the top of a building with an initial velocity of 50 meters per second is modeled as h=-4.9t^2+50t+x, where h is the height in meters of the object at a given time, t is the time in seconds, and x is the height of the building in meters. If the object hits the ground after 21 seconds, what is the approximate height, in meters, of the building?
