A student's head is bent over her physics book. The head weighs P = 25.6 N and is supported by the muscle force F exerted by the neck extensor muscles and by the contact force Fc exerted at the atlantooccipital joint. Given m that the magnitude of Fm is 60.0 N and is directed 35.0° below the horizontal.
