3. The net force exerted by a woodpecker's head when its beak strikes a tree can be as large as 4.90 N, assuming that the bird's head has a mass of 50.0 g.
Assume that two different muscles pull the woodpecker's head forward and
downward, exerting a net force of 4.90 N. If the forces exerted by the muscles
are at right angles to each other and the muscle that pulls the woodpecker's
head downward exerts a force of 1.70 N, what is the magnitude of the force
exerted by the other muscle? Draw a free-body diagram showing the forces
acting on the woodpecker's head.
