A lamp is placed on the ground at a distance of 17 feet from the point at which a rocket will be launched into the air. If the rocket travels straight up at a rate of 7 feet per second, determine the rate of change of the angle of elevation (0) from the lamp to the rocket when the rocket is at a height of 43 feet.
