A force Fx acts on a particle that has a mass of 1.30 kg. The force is related to the position x of the particle by the formula Fx = Cx3, where C = 0.495 if x is in meters and Fx is in newtons. Calculate the work done by this force on the particle as the particle moves from x = 2.87 m to x = 1.66 m.

A solid lead sphere of radius 10 m (about 66 feet across!) has a mass of about 57 million kg. If two of these spheres are floating right next to each other (centers 20 m apart) in deep space, the gravitational attraction between the spheres is only 540 N (about 100 pounds). How large would this gravitational force be if the distance between the centers of the two spheres were doubled?
