An object of mass m is held at rest a distance Re above the earth’s north pole, where Re is the radius of the earth and g is the accelera- tion due to gravity on the surface. If the object is allowed to fall, with what speed does it hit the surface? Ignore the mo- tion of the earth around the sun, and friction with the earth’s atmosphere.
