A 15 kg object is on a flat surface at rest. Its contact with the surface can be characterized by a coefficient of static friction of 0.6 and a coefficient of kinetic friction of 0.3. A. If a person applies a horizontal force of magnitude 50 N, what is the magnitude of the friction force exerted by the surface on the object? B. If a person applies a horizontal force of magnitude 250 N, what is the magnitude of the friction force exerted by the surface on the object?
