Question

A 5.00kg piece of wood slides on a surface shown in the figure to the right. The curved sides are perfectly smooth, but the rough horizontal bottom is 30m long and has a kinetic friction coefficient of 0.100 with the wood. The piece of wood starts at rest 10.0m above the rough bottom aqnd it will move back and forth across the bottom until it finally comes to rest. (a) If the left side of the rough bottom is at x=0m, where will the wood eventually come to rest ? (x=?) (b) What is the total amount of work done by friction? (note: must use conservation of energy formulas) couldn't insert image.. left to right horizontal line, curved up slightly on both ends.

Explanation / Answer

figure ??? please post the figure
