Five objects of the same mass M: a hoop (radius
Five objects of the same mass M: a hoop (radius R), a solid sphere (radius R), a thin-hollow sphere with the same radius as that of the sphere (radius R), a solid cylinder (radius R), and a small point-like particle, all race down a ramp of height h and slope (45 degree). The frictions are just large enough to cause the first four objects to roll, but is negligible to the particle so it comes down the ramp friction free (approximately). Determine the rank of the race: the hoop_______, the solid sphere_______, hollow sphere_______, solid cylinder_______and the particle_______.
(A) First, (B) second, (C) third, (D) fourth, (E) fifth, (F) Cannot be determined, (G) None of these.
