Find the resulting force (magnitude and direction).

Problem 2: An applied force of 20 N is used to accelerate an object to the right across a frictional surface. The object encounters 10 N of friction. Use the diagram to determine the normal force, the net force, the coefficient of friction (u) between the object and the surface, the mass, and the acceleration of the object. (Neglect air resistance.) Fnorm Friet =10 N Fapp = 20 N Fgrav=100 N m = a = Fnet=
