The figure shows a 0.424-kg block sliding from A to B along a frictionless surface. When the block reaches B, it continues to slide along
the horizontal surface BC where the kinetic frictional force acts. As a result, the block slows down, coming to rest at C. The kinetic
energy of the block at A is 35.0 J, and the heights of A and B are 12.2 and 6.30 m above the ground, respectively. (a) What is the value
of the kinetic energy of the block when it reaches B? (b) How much work does the kinetic frictional force do during the BC segment of
the trip?
