An archer shoots an arrow. Consider the action force to be the bowstring against the arrow. The reaction to this force is the

• arrow's push against the bowstring

• weight of the arrow

• friction of the ground against the archer's feet

• air resistance against the bow

• grip of the archer's hand on the bow
