10. A box has a weight of 150 Newtons. The
11. You tie another box onto the one you were dragging around in problem 10. Box #2 is on wheels (frictionless), which is attached to Box #1 (50 N of friction), and you are dragging the whole thing by pulling on Box #1 with 150 N of force. Draw a picture, use Newton’s 2nd Law to find the acceleration of the whole thing, then apply it again to find the tension in the cord between Box #1 and Box #2.
