Answer to Question #99254 in Physics for criss

Question

The figure below shows a clawhammer as it is being used to pull a nail out of a horizontal board. A force of magnitude 156 N is exerted horizontally as shown. (Assume that the force the hammer exerts on the nail is parallel to the nail and perpendicular to the position vector from the point of contact. The x-component of this force's lever arm is 5 cm.)

(a) Find the force exerted by the hammer claws on the nail. (Enter the magnitude.)

(b) Find the force exerted by the surface at the point of contact with the hammer head. (Assume the positive x-axis is to the right.)
magnitude:
direction:
