To prevent a box from sliding down an inclined plane, student A pushes on the box in the direction
parallel to the incline, just hard enough to hold the box stationary (top Figure). In an identical situation
student B pushes on the box horizontally (bottom Figure). Regard as known the mass m of the box,
the coefficient of static friction µs between box and incline, and the inclination angle q (a) Determine
the force FA has to exert. (b) Determine the force FB has to exert
