A \( 2.5 \mathrm{~kg} \) piece of wood slides on the surface shown in the accompanying figure (Figure 1). All parts of the surface are frictionless, except for a 30 -m-long rough segment at the bottom, where the coefficient of kinetic friction with the wood is \( 0.20 \). The wood starts from rest friction with the wood is 0. \( 4.5 \mathrm{~m} \) above the bottom. \( \nabla \) Part A Figure X Incorrect; Try Again; 5 attempts remaining Part B How much work is done by friction by the time the wood stops? Express your answer in meters. A \( 2.5 \mathrm{~kg} \) piece of wood slides on the surface shown in the accompanying figure (Figure 1).
