Question

A horse harnessed to a wagon refuses to pull citing Newton’s third law of motion as grounds for not being able to possibly be able to move the wagon. The horse, incorrect in his reasoning, can pull the wagon because:

- the law only applies to static cases

-after it gives a jerk and the wagon is moving, the horse’s pulling force will be greater than the reaction to this force

- the action and reaction forces are acting on different

- the wagon cannot possibly pull back with a force equal in magnitude to the pulling force - after friction is overcome, the reaction force is less than the pulling force

Answer 1

Correct option: the wagon cannot possibly pull back with a force equal in magnitude to the pulling force - after friction is overcome, the reaction force is less than the pulling force
