A 49-n hammer head is stopped from an initial downward, Ask an Expert

Academics

A 4.9-N hammer head is stopped from an initial downward velocity of 3.2 m/s in a distance of 0.45 cm by a nail in a pine board. In addition to its weight, there is a 15-N downward force on the hammer head applied by the person using the hammer. Assume that the acceleration of the hammer head is constant while it is in contact with the nail and moving downward.

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.
