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?
