B3-SCT86: Box PULLED ON ROUGH, HORIZZONTAL SURFACE-FRICTIONAL FORCE ON BOX A 100 N box is initially at rest on a rough, horizontal surface. The coefficient of static friction is 0.6, and the coefficient of kinetic friction is 0.4. A constant 35 N horizontal force to the right is applied to the box. Four students are discussing the frictional force exerted on the box by the rough surface 1 second after the force is first applied: 35 N 100 N Al: "The frictional force is 60 N since the box will not be moving and the coefficient of static friction is 0.6 with a normal force of 100 N." "The frictional force is 40 N since the coefficient of kinetic friction is 0.4 and there is a normal force of 100 N." Brianna: Carlos: "The frictional force is 35 N since the box will not be moving and the frictional force will cancel out the applied force of 35 N." "It is 40 N for the kinetic frictional force and 60 N for the static frictional force. The normal force is 100 N and the coefficient of kinetic friction is 0.4, giving 40 N for the kinetic friction. Similarly, for the static frictional force it is 60 N since it has a coefficient of static friction of 0.6." David: With which, if any, of these students do you agree? Al Brianna Carlos David None of them Explain your reasoning.
