Hello. Here is the problem I am stuck on. Any helpwill be awesome. While preparing its budget for the next fiscal year, NASAwants to report to the nation a rough estimate of the cost (perkilogram) of launching a modern satellite into near-Earth orbit.You are chosen for this task, because you know both physics andaccounting. (a) Determine the energy, in kW·h,necessary to place a 1.0-kg object in low-Earth orbit. In low-Earthorbit, the height of the object above the surface of Earth is muchsmaller than Earth's radius. Take the orbital height to be340 km.1 kW·h
(b) If this energy can be obtained at a typical electrical energyrate of $0.18 / kW·h, what is theminimum cost of launching a 355 kgsatellite into low-Earth orbit? Neglect any effects due to airresistance.
