I need help with this question and answering all the steps Calculate the minimum amount of work needed to move a 500-kg rocket payload from Earth's surface to the ISS in orbit 400,000m above Earth's surface. Draw a sketch of the situation, labeling all of the physical quantities given in the problem. Identify your system in the sketch. Make sure both the initial and final states are represented in your sketch. Be sure to include all values you need to look up (such as the mass of Earth) in your sketch. Draw a work-energy bar chart for this process. Take the rocket at rest on Earth's surface as your initial state and when the rocket is at rest at the ISS. Solve for the minimum amount of work needed to move the payload to the ISS. Start with general equations and explain what you are doing and why you did what you did. Evaluate your solution. Describe how you evaluated your answer and whether or not you think your answer is reasonable.
