Hey everyone,
I need help deciding on which formula to use for a specific question. The marking guideline records: calculates centripetal force via correct formula, calculation and answer.
I need to find the force acting on a satellite, in this situation the satellite is 450 kg and is orbiting 35,9000 km above the earth. It is one part of a multipart question, the next questions ask what the velocity is and what is the orbital period. Would I be correct using centripetal force = mv^2 / r, by using the velocity I calculated in the second part of the question or do I have to use F = GMm / r^2
