2. Consider an armchair sitting on the flat surface of a floor. The armchair has a mass of 25.0 kg. The coefficient of static friction between the armchair and the floor is 0.54, and the coefficient of kinetic friction is 0.32 (a) In an attempt to push the armchair, you apply a force in a horizontal direction, starting at 0 N and increasing, past the point where the armchair begins to move. Plot the force of friction as a function of your applied force. (b) Suppose that you increase the force you apply until the armchair begins to move, and then keep applying a constant force of that magnitude. Draw and label armchair free body diagram, including showing the direction of acceleration, if any. (c) Find the magnitude of the acceleration for the case in (b).
