The rocket in a rocket-powered airplane generates a steady force of 10,000 N in the forward direction and the plane moves horizontally at a constant velocity of 300 m/s through the air. The rocket engine is upgraded so that it now provides a forward force of 90,000 N. What is the new constant velocity of the plane? You cannot neglect air resistance in this question. O 200 m/s 300 m/s 400 m/s O 600 m/s O 900 m/s
