A 2.00-kg piece of wood slides on the surface shown. The curve slides are perfectly smooth but the rough horizontal bottom is 30m long and has a kinetic coefficient of 0.20 with the wood. The piece of wood starts from rest 4.0m above the rough bottom. Let point X be the wood located at the edge of the curve; point Y be the point just before the wood slides the rough part of the surface, and point Z be the point when the wood stopped at the rough part of the surface. a. Calculate total mechanical energies at pt. X, Y, and Z. b. Calculate the maximum distance the wood can travel along the rough bottom. d. Is the total mechanical energy conserved from points X to Z? Explain. e. Is the total energy conserved from points X to Z? Explain
