One block rests upon a horizontal surface. A second identical block rests upon the first one. The coefficient of static friction between the blocks is the same as the coefficient of static friction between the lower block and the horizontal surface. A horizontal force is applied to the upper block, and its magnitude is slowly increased. When the force reaches 49.3 N, the upper block just begins to slide. The force is then removed from the upper block, and the blocks are returned to their original configuration. What is the magnitude of the horizontal force that should be applied to the lower block, so that it just begins to slide out from under the upper block?

Your friend asks for help moving a box across the apartment floor and tells you that the box weighs 422 N. Your friend also informs you the box, currently motionless, has a coefficient of static friction (us=0.42) and a coefficient of kinetic friction (u=0.31) between it and the floor. You apply a horizontal force of 208 N on the box. Calculate the magnitude of the frictional force, f, acting on the box while you apply that force.
