\n" ); document.write( "\n" ); document.write( "A launched rocket has an altitude, in meters, given by the polynomial h+vt-4.9t^2, 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 70 meters high with an initial upward speed of 80 meters per second, what will its height be after 2 seconds?
