I need help solving this question. A rocket starting from rest rises vertically and accelerates at a constant rate of 13 m/s2 for 7 min. At this point the engine of the rocket accidently fails and completely shuts down. (Neglect air resistance and any variation in the acceleration due to gravity) a) What is the speed of the rocket when the engine shuts down? b) How high is the rocket above the ground at the point where the engine shuts down? c) How much higher will the rocket rise after the engine fails? d) What is the total time of the rocket in air? e) What is the average speed of the rocket for the entire trip?
