A small ball starts moving from A over a fixed track as shown in the figure. Surface AB has friction. From A to B the ball rolls without slipping. Surface BC is frictionless. KA, KB and KC are kinetic energies of the ball at A, B and C respectively. Then
- hA > hC ; KB > KC
- hA > hC ; KC > KA
- hA = hC ; KB = KC
- hA < hC ; KB > KC
Answer
(B) h A > h C ; K C > K A
