Three wagons, each of mass m are being pulled by an engine exerting a froce F on the lead wagon. What is the fore exerted on the last wagon by the middle wagon?

80 railway wagons all of same mass 5xx10^(3) kg are pulled by an engine with a force of 4xx10^(5) N. The tension in the coupling between 30 th and st 31st wagon from the engine is :-

A horse is urged to pull a wagon the horse refuses to try, citing Newton's third laws as a defense: the pull of the horse on the wagon is equal to but opposite the pull of the wagon on the horse. "If I can never exert a greater force on the wagon than it exerts on me, how can I ever start the wagon moving ?" Asks the horse. How would you reply ?

A locomotive (engine) pulls a series of wagons. Which is the correct analysis of the situation?

Two blocks A and B of mass m_A and m_B respectively are kept in contact on a frictionless table. The experimenter pushes the block A from behind so that the blocks accelerate. If the block A exerts a fore F on the block B, what is the force exerted by the experimenter on A?
