1. The problem statement, all variables and given/known data Two frats compete in a tug of war. Each team has 5 players of mass 80kg each. Each person is capable of pulling with 100N of force. The force of one team decays according to F(t) = F0(e^(-t/2)) and the other, F(t) =F0(e^(-t/1)). What is the position of the (very lightweight) rope as a function of time? 2. Relevant equations Fnet = ma 3. The attempt at a solution (m)(a) =F0(e^(-t/1)) - F0(e^(-t/2)) where F0 = 500 for both team. I am not sure if the mass is simply 5*80 or double that because of the two teams. Then I suppose you could integrate this and find x from the acceleration.
