You have a small globe, which is mounted so that it can spin on the polar axis and can be spun about a horizontal axis (so that the south pole can be on top). Give the globe a quick spin about the polar axis, and then, before it stops, give it a spin about the horizontal axis. Are there any points on the globe that are at rest?(A) There are two points, fixed on the globe, that are at rest.(B) There are two points that are instantaneously at rest, but these two points move around the globe in an apparently random fashion.(C) At some times two points are instantaneously at rest,(D) There are no points at rest until the globe stops spinning.
