1) Why doesn't the coefficient of friction have any units? 2) A rop can withstand 750 Newtons. If 2 people in opposite directions pull with a force of 500 newtons will the rope break? 3) In a tug-of-war Newtons 3rd law states that any action causes an equal yet opposite reaction. Explain how a tug-of-war match can be won using this law. I put because one side may loosen their grip, or weigh less and therefore have less friection on their side, or may be weaker so thery cannot possible apply the force the other side can without sliding. 4) A fisherman uses a line that has a test value of 50 pounds. If he pulls the fish upwards at 2m/s/s how much does the fish weigh at least? I put 25 lbs.
