Calculate how much work is required to launch a spacecraft of mass m from the surface of the earth (mass me, radius re) and place it in a circular low each orbit, that is, an orbit whose altitude above the earth's surface is much less than re. (as an example, the international space station is in low earth orbit at an altitude of about 400 km, much less than re=6380 km.) you can ignore the kinetic energy that the spacecraft has on the ground due to the earth's rotation. express your answer in terms of the variables m, me, re and appropriate constants. b) calculate the minimum amount of additional work required to move the spacecraft from low earth orbit to a very great distance from the earth. you can ignore the gravitational effects of the sun, the moon, and the other planets. express your answer in terms of the variables m, me, re, and appropriate constants.
