An object of mass M, on the end of a string, is moving in a uniform circle on a horizontal, frictionless table as shown. The string is then slowly pulled through a small hole in the table. Using the small hole as the reference point: (a) the angular momentum of M remains constant. (b) the angular momentum of M decreases. (c) the kinetic energy of M remains constant. (d) the kinetic energy of M decreases. e) None of the above pull
