A solid sphere radius starts from rest at the top of an incline of height h and length I and moves down. The force of friction betwéen the sphere and the inclnie is F. The friction is insufficient to prevent slipping. The kinetic energy of the sphere at the bottom of the incline is K. Then (a) The work done by the frictional force is F!. (b) The head proğuced is Fl. (c) K= mgh - E (d) K>mgh-F 66.
