A farmer is trying to haul three 500-kg trailers connected together with identical ropes that will break if their tension exceeds 3000 N . The first trailer is connected to his tractor with a rigid hitch. Part A If the tractor has to overcome a frictional force of 900 N per trailer to start them moving, what is the minimum force the tractor must exert on the first trailer to get them all rolling if the ropes are taut? Express your answer with the appropriate units. Part B What is the maximum force the tractor can exert without breaking any rope? Express your answer with the appropriate units.
