Hi there. The question I need help with is #11. I understand you guys can only answer one question at a time. I know the answer to #10 is 500J. #10 Is just a reference to do #11, i just don't know how to do it #11. Thanks.10. (Reference) A box has a weight of 150 Newtons. The force of friction on the box is 50 Newtons if it is dragged across a level floor. How much work is done on the box to drag it 10 meters across the level floor?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.
