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. In an identical situation, student B pushes on the box horizontally. If the weight of the box w= 220. N, the angle made by the incline with the horizontal ?=25, and the coefficient of static friction µs=0.16, who has the easier job?
