Work done by friction when a bullet embeds in a wooden block

[rajkirann]

Physics problem?
Suppose you shoot a bullet of mass 2g into a wooden block of mass 0.498 kg resting on the table. the bullet gets stuck in the wood, and the block slides a distance of 0.2m before it comes to rest again. how much work is done by the friction if the block with the bullet slides a distance of 0.2m on te table with a frictional coefficient of 0.4?

Hint: What's the definition of work?

Check the definition of work. The relationship between the coefficient of friction and the normal is basically all you need to know because they gave you the distance.
