1. The problem statement, all variables and given/known data A girl pulls her 4.00kg sled connected to a weightless rope. She pulls the rope on the sled and it goes faster and faster on a frictionless ice surface. The sled has an acceleration of 2.50m/s^2. What is the tension on the rope? What is the net force? 2. Relevant equations F = ma 3. The attempt at a solution F(net) = 4.00kg*2.50m/s^2 = 10.0N T = 4.00kg*2.50m/s^2 = 10.0N If my answers are correct, where is the reaction force to F(net) for Newton's 3rd law? I understand that the reaction force to the tension is the what the rope is attached to, but then what is the reaction force to F(net)?
