A 2.00 kg piece of wood slides on the surface shown in the accompanying figure. All parts of the surface are frictionless, except for a 30.0 m -long rough segment at the bottom, where the coefficient of kinetic friction with the wood is 0.200. The wood starts from rest 3.00 m above the bottom.
Where will the wood eventually come to rest?
How much work is done by friction by the time the wood stops?
