Question: A hammer head H having a weight
A hammer head H having a weight of 0.25 lb is moving vertically downward at 40 ft/s when it strikes the head of a nail of negligible mass and drives it into a block of wood. Find the impulse on the nail if it is assumed that the grip at A is loose, the handle has a negligible mass, and the hammer stays in contact with the nail while It comes to rest. Neglect the impulse caused by the weight of the hammer head during contact with the nail.
