:) PART ONE
The figure shows a claw hammer as it pulls a
nail out of a horizontal board. If a force of magnitude 74.3 N is exerted
horizontally as shown, find the force exerted
by the hammer claws on the nail. (Assume
that the force the exerts on the nail
is parallel to the nail).
Answer in units of N.
PART TWO
