Please help me answer c: apparantly my answer is not correct.THank you.
The problem of finding the work done in lifting a payload from the surface of the moon is another type of work problem. Suppose the moon has a radius of R miles and the 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 pay load Js given by the following relation: required force = f(x) = -- pounds The total 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) How much work would be needed to raise the payload from an altitude of R miles above the surface (i.e., x= 2R) to an altitude of 2R miles above the surface work mile-pounds How much work would be needed to raise the payload from the surface of the moon (i.e., x- R) to an altitude of 5R miles above the surface of the moon ? work
