1. The problem statement, all variables and given/known data A spy satellite of mass m is in a circular orbit with radius R and velocity v around the earth. One of the satellites thrusters suddenly fires giving it an additional velocity v in the outward radial direction (same v). What is the new total energy of the satellite? What is the new orbit of the satellite? 2. Relevant equations mv^2/r GMm/r^2 -K=.5U 2K+U=0 3. The attempt at a solution I honestly don't really have an idea how to even set up the problem. From what I understand mv^2=GMm/r^2 for circular orbit which should I could then use to find the energy, but I don't know how the velocity increasing radially will affect this. Any helpful nudge in the right direction would be greatly appreciated.
