Question reads: A rocket of mass 1000 kg is being fired to a height of 5000m. The rocket engine shuts off when the rocket reaches a height of 1000m, and the rocket coasts up to 5000m. a) what velocity must the rocket have at the 1000m point to enable it to reach 5000m ? b) what acceleraation did the rocket experience while the engine was on? and off? so this is a very new question for me as i was previously dealing with tension and friction forces along the plane. im not very sure how to start questions like this one where i need to combine kinematics. will i need to find the acceleration first? i know that the forces acting on the rocket is force applied [up] and gravitational force [ down]. please further guide me with this problem as i have no clue as of this time.
