A nail gun fires a nail into a piece of wood. The nail is going a velocity of 9.0 m/s right before entering the wood. The mass of the nail is 0.060 kg and the average force on the nail is 6.1 N.
(a) Find the acceleration of the nail.
(b) How far into the wood does the nail go?
(c) From entering the wood, how long does it take the nail to come to a stop?
