Let us say that a regular shoot out is happening, and the gunman was shooting a criminal and missed. The gunman fired a shot and it hit a wooden block instead and not the criminal and the bullet remained inside the wooden block. The bullet's mass is 7.00kg and the wooden block's mass is 1.25kg. The bullet travelled 1.30m into the wooden block with a coefficient friction .480. What would be the initial speed of this bullet? Thank you. Let us know please.
