A 4.9-N hammer head is stopped from an initial downward velocity of 3.2 m/s in a distance
Question:
(a) Draw a free-body diagram for the hammer head. Identify the reaction force to each action force in the diagram.
(b) Calculate the downward force F exerted by the hammer head on the nail while the hammer head is in contact with the nail and moving downward.
(c) Suppose the nail is in hardwood and the distance the hammer head travels in coming to rest is only 0.12 cm. The downward forces on the hammer head are the same as on part (b). What then is the force F exerted by the hammer head on the nail while the hammer head is in contact with the nail and moving downward?
