WebThis means that the net external force on her is in the direction opposite to F feet on wall. This opposition is the result of Newton’s third law of motion, which dictates that the wall exerts a force F wall on feet on the swimmer that is equal in magnitude but that acts in the direction opposite to the force that the swimmer exerts on the wall. http://www.edwardbosworth.com/My5155Text_V07_HTM/MyText5155_Ch02_V07.htm
