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?
W = F x d
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?
