A 0.22LR caliber bullet has a mass of 31 grains (2.00 g) and a muzzle velocity of 1750 ft/s (530 m/s). The bullet is fired into a door made of a double thickness of pine boards, each with a thickness of 0.75 in. The average stopping force exerted by the wood is 960 N. How fast (in m/s) would the bullet be traveling after it penetrated through the door? m/s
