Greetings. I have been a bit confused with kinetic energy and potential energy but I thought I was over my confusion until satellites in orbit appeared. I'm dealing with a problem with a few parts and I'm stuck on part B. Part A asked me to calculate the PEg of the satellite, with I could easily do using the equation PEg= - (Gm1m2)/R^2 . The following question then asked me what the kinetic energy and velocity of the satellite is. I only have the mass of the satellite and the answer from the first part to work with. I don't need the answer, just a point in the right direction. Thank you in advance!
