A uniform board of length L=.75mis sliding along a smooth, frictionless horizontal plane. The boardslides across a boundary with a rough horizontal surface. Thecoefficient of kinetic friection between the board and anothersecond surface is μk= .31.The board has an initial speed of v=2.5m/s. How far past theboundary is the left end of the board when the board comes to rest?The answer was .654m, but I'm not getting any answer close to it,please help!
