A wedge of mass m = 25.0 kg is located on a plane that is inclined by an angle ? = 20.6° with respect to the horizontal. A force F = 316.3 N in the horizontal direction pushes on the wedge, as shown in the figure. The coefficient of kinetic friction between the wedge and the plane is 0.156. What is the acceleration of the wedge along the plane? (Take the positive direction to be up the plane.)
