Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

2 A claw hammer is used
to pull a nail out of a board
(Fig. 11.38). The nail is at an
angle of 60° to the board, and a
force F, of magnitude 500 N
applied to the nail is required to
pull it from the board. The ham-
mer head contacts the board at
0.300 m
point A, which is 0.080 m from
where the nail enters the board.
A horizontal force F, is applied
to the hammer handle at a dis-
tance of 0.300 m above the
60°
board. What magnitude of force
F, is required to apply the
required 500-N force (F) to the
nail? (You can ignore the weight of the hammer.)
