A 2g bullet hits a 5kg wood block, which hangs from a 1.5m long string. This causes the block to swing through an arc of 5°. What was the speed of the bullet before it hit the block?
I know that I need to use the momentum and circular motion equations. Can someone tell me what I need to do with the 5°?
