A launched rocket has an altitude, in meters, given by the polynomial hplus+vtminus-4.9tsquared2 , where h is the height, in meters, from which the launch occurs, at velocity v in meters per second, and t is the number of seconds for which the rocket is airborne. If a rocket is launched from the top of a tower 140140 meters high with an initial upward speed of 4040 meters per second, what will its height be after 33 seconds?
