Find the magnitude F of the force that the wooden block exerts on the nail, assuming that this force is independent of the dept
of penetration of the nail into the wood. You may also assume that vo > √2gL, so that the change in the hammer's
gravitational potential energy, as it drives the nail into the block, is insignificant.
Express the magnitude of the force in terms of M, vo, and L.
