6. An annular disk of mass M, inner radius a and outer radius b is placed on a horizontal surface with coefficient of friction , as shown in the figure. At some time, an impulse Jox is applied at a height h above the center of the disk. If h = hm then the disk rolls without slipping along the x-axis. Which of the following statement(s) is (are) correct? L. (A) For = 0 and a 0, hm = bl2 (B) For 0 and a b, hm = b (C) For h = hm, the initial angular velocity does not depend on the inner radius a (D) For = 0 and h = 0, the wheel always slides without rolling 7.
