31. A massive block was pulled at an angle of 30° in a horizontal rough surface by a force of magnitude F enough for the block to move. If we set the +x-axis at the right, which of the following statements is true about the forces acting on the block? 30⁰ F rough A. The direction of the frictional force experienced by the block is to the left. B. The normal force's direction is 30° above the +x-axis. C. The block will not experience friction since F is just enough to move the block. D. The direction of the weight of the block is about 210° from the x-axis.
