Two forces are applied to a 4.0 kg cart on a rough surface as shown. At a certain instant, force A is 32 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.

As you will see in a later chapter, forces are vector quantities, and the total force on an object is the vector sum of all forces acting on it. In the figure below, a forceF1of magnitude 6.40 units acts on a crate at the origin in a direction θ = 28.0° above the positive x-axis. A second force F2 of magnitude 5.00 units acts on the crate in the direction of the positive y-axis. Find graphically the magnitude and direction (in degrees counterclockwise from the +x-axis) of the resultant force F1 + F2. magnitude units direction° counterclockwise from the +x-axis
