1. The problem statement, all variables and given/known data Both the following statements are true; explain them. Two teams having a tug of war must always pull equally hard on one another. The team that pushes harder against the ground wins. 2. Relevant equations Friction = uN 3. The attempt at a solution For the first statement...During a tug of war the teams must pull equally hard, or else one of them would have won, right? As for the second statement : By pushing harder against the ground, the normal force experienced, hence friction, would be larger, so the competitors slip less easily, then? (I kinda get the concept in mind...but how to explain it in words??) Thanks in advance!
