Chapter 8, Problem 57RQ

A spacecraft utilized Earth’s gravity and increasing large orbital paths around Earth to minimize the use of propellant to escape Earth’s orbit. This method involves the use of several short firings of the engines to push the rocket a smaller distance rather than one long firing with a large consumption of fuel to push the rocket the entire distance. One of the maneuvers used 440 newtons [N] of thrust for 570.6 seconds [s], resulting in a rise in orbit of 7055 miles [mi]. How much power, in units of watts [W], did this maneuver require? Express the answers using an appropriate SI prefix such that there are only one, two, or three digits shown to the left of the decimal. Assume the process is 100% efficient.
