You want to move a heavy box with mass 30.0 kg across a carpeted floor. You pull hard on one of the edges of the box at an angle 30∘ above the horizontal with a force of magnitude 240 N, causing the box to move horizontally. The force of friction between the moving box and the floor has magnitude 41.5 N . 1. What is the box's acceleration just after it begins to move? 2. Draw a free body diagram for the box, assuming that the positive-x axis is to the left, and the positive-y axis is upward.
