A model rocket is launched straight upward with an initial speed of 44.0 m/s. It accelerates with a constant upward acceleration of 2.50 m/s? until its engines stop at an altitude of 130 m. (a) What can you say about the motion of the rocket after its enbines stop? The rocket will continue to progress upward, after the engine stops, due to gravity until the previous acceleration runs out. Eventually the force of gravity will overcome the momentum of the rocket, the rocket will reach maximum height, and come back down to earth. a This answer has not been graded yet. (b) What is the maximum height reached by the rocket? (c) How long after liftoff does the rocket reach its maximum height? (d) How long is the rocket in the air?
