Two drivers, one owning a large Cadillac and the other owning a small Volkswagen, make a bet. The W owner bets that his car can pull as hard as the Cadillac. They chain the two rear bumpers together in a large empty parking lot. Each driver gets
into his vehicle and applies full power. The Cadillac pulls the VW backward all over the lot. The WW driver later claims that his
car was pulling on the chain as hard as the Cadillac all the time. (Assume that the chain has negligible mass.) What does
Newton's third law say about this claim?
