Action-Reaction PairsMediumQuestion 30237

Question

A horse pulls a cart. If the cart pulls the horse backward with equal force, why does the system accelerate?
  1. A
    Because action-reaction are on the same object
  2. B
    Because the action and reaction act on different objects, and other forces act on each
    Correct
  3. C
    Because the reaction force is less
  4. D
    Because friction is ignored

Correct answer

Because the action and reaction act on different objects, and other forces act on each

Explanation

Action-reaction pairs act on different objects. The horse accelerates due to the friction from the ground exceeding the cart's pull on it.
