Question

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 400 newtons​ [N] of thrust for 540.6 seconds​ [s], resulting in a rise in orbit of 7 comma 058 miles​ [mi]. How much​ power, in units of watts​ [W], did this maneuver​ require? Express the answer 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.
