Suppose the moon has a radius of R miles and a payload weighs P pounds at the surface of the moon (at a distance of R miles from the center of the moon). When the payload is x miles from the center of the moon (x ≥ R), the force required to overcome the gravitational attraction between the moon and the payload is given by the following relation:
required force = f(x) = R2P
For example, the amount of work done raising the payload from the surface of the moon (i.e., x = R) to an altitude of R miles above the surface of the moon (i.e., x = 2R) is
work = b
How much work would be needed to raise the payload from the surface of the moon (i.e., x = R) to the "end of the universe"?
work = mile-pounds
The solution is... View the full answer
