During a test a rocket is traveling upward at a constant velocity. When it is 40 m from the ground its engine fails. Which of the following is always true? COCO) If air resistance is neglected, it would continue to travel upward. ZOZO) If gravitational acceleration is removed, it would maintain its constant speed. RORO) If gravitational acceleration is weak, it would maintain its constant speed. TOTO) The rocket will immediately fall to the ground at the instant the engine fails because it is massive
