Two forces are applied to a 4.0 kg cart on a rough surface as shown. At a certain instant, force A is 12 N to the right, and force B is 20 N to the left. The friction force is 2.0 N. What is the acceleration of the cart at this instant, in m/s2? (Hint: What is the direction of the friction in this case? Draw a free-body diagram.) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
