6.0-kg block slides from position A down to a frictionless curve to position B.
At B, a friction force opposes the motion of the block so that it comes to a stop 2.5-m from B. Calculate (a) the speed of the block at point B using work-energy theorem and (b) the coefficient of kinetic friction between the block and the surface after position B.
