A 7 g bullet is fired into a 13.43 kg wood block that is at rest on a wood table. The block, with the bullet embedded, slides 5.92 cm across the table. What was the speed of the bullet?
The Attempt at a Solution
I am not sure how to solve this because i am not given a coeffieicent of friction of wood on wood. I tried one that i found online (.48) but it didnt work then i tried .25 and that didnt work either. I thought i need this so i can find the acceleration so i can find out delta t so I can find the velocity of the wood with the bullet in it. But i came up with this equation to solve for the velocity of the bullet......
