A 10 g bullet with a horizontal velocity...

A 10 g bullet with a horizontal velocity of 300 `"m.s"^(-1)` , hits a wooden block of mass 290 g. After collision, the block and the bullet move together and come to rest after travelling 15 m horizontally. What is the coefficient of friction between the block and the horizontal plane on which it is kept?
