Compute the work w against the earth's gravitational field required to move a satellite of mass m = 1000 kg along any path from an orbit of altitude 5000 km to an orbit of altitude 6000 km. (use 6.4 × 106 m for the radius of the earth and k = 4 × 1014 m3/s2. if you enter your answer in scientific notation, round the decimal value to two decimal places. use equivalent rounding if you do not enter your answer in scientific notation.)
