A student's head is bent over her physics book. The head weighs 50.0 N and is supported by the muscle force F m exerted by the neck extensor muscles and by the contact force Fc exerted at the atlantooccipital joint. Given that the magnitude of F m is 60.0 N and is directed 35° below the horizontal, find
(a) The magnitude and
(b) The direction of Fc.
