Objective: To measure the force produced by the Rocket (Atlus-V) engine, in order to get the rocket into space. Introduction: This NASA footage shows the Atlas V rocket launching the Mars Science Laboratory (aka Curiosity Rover). This rocket launched the Curiosity rover on its 8.5 month long journey to Mars. The first part of the trip was to use the ATLAS-V rocket to launch the rover into orbit around earth. The first few seconds of this trip are shown in the link attached. Pre-Lab: Let's start by calculating what acceleration the rocket must produce to launch into earth orbit. In order to attain orbit around earth, the ATLAS-V rocket must accelerate up to a speed of about 7700m/s in about 11 minutes. a) What average acceleration is required to accomplish this? b) If the mass of the rocket + fuel is 3.05x105 kg, what is the applied force of the engine?
