Bonus Question.... So my teacher gave us this question... where he describes that. "We have a heavy box, we want to move it but can NOT apply horizantal force (meaning CANT get on your knees and push it) we would have to either push down on it at an angle to move it, or pull up and push (or pull he didnt specify), which method is easier?" Ok well I would say that pulling up on it would be easier because it reduces the amount of friction, right? Pushing down on it, increases the friction... But the hard part is... Our answer has to be in the form of an algebraic equation.. How do I go about converting my answer into algebra (assuming my answer was right). He said it's a grade 12 problem, but we should be able to do it... (using our knowledge of physics, grade 11 formulas ..) Ive seen some grade 12 problems... the only difference right now for me between grade 11 and 12 problems is that they throw in some trig.... Would I have to use trig here because you're pulling up, the surface isn't horizantal? Or could I use grade 11 knowledge and make an equation?
