Part one
the figure shows a claw hammer as it pulls a
nail out of a horizontal board. if a force of magnitude 62.5 n is exerted
horizontally as shown, find the force exerted
by the hammer claws on the nail. (assume
that the force the hammer exerts on the nail
is parallel to the nail).
answer in units of n.
part two
find the force exerted by the surface on the
point of contact with the hammer head. assume that the force the hammer exerts on the nail is parallel to the nail.
answer in units of n.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
