A ball moves over a fixed track as shown in the figure.

A ball moves over a fixed track as shown in the figure. From A to B the ball rolls without slipping. Surface BC is frictionless. K, KB and Ke are kinetic energies of the ball at h A, B and C, respectively. Then (A) hA> hc; KB > Kc (B) h> hc; Kc > KA (C) hA=hc; KB = Kc (D) hAhc: KB > Kc B
