Three identical solid sphere moves down three incline A, B and C - all of the sme dimensions. A is without friction, the friction between B and sphere is sufficient to cause rolling without slipping, the friction between C and sphere causes rolling with slipping. The kinetic energies A,B,C at the bottom of the inclines are E_(A),E_(B),E_(C)

Answer»

`E_(A)=E_(B)=E_(C)`
`E_(A)=E_(B)gtE_(C)`
`E_(A)gtE_(B)gtE_(C)`
