1. The problem statement, all variables and given/known data A 1.0 kg block of wood is lifted a distance of 1.5 m from the floor and placed on a wooden shelf. A steady horizontal force is then applied to the block, causing it to slide sideways along the shelf a distance of 1.5 m at a uniform velocity. The kinetic coefficient of friction for the block when it is on the shelf is 0.23. How much work is done sliding the block along the shelf? 2. Relevant equations W = F x d 3. The attempt at a solution Is there some formula I should be using? I tried W = F x d but that doesn't give me the right answer of 3.4 J . Help?
