MCQ
In a tonga, horse pulls a wagon. Which is the correct analysis of the situation?
  • A
    The tonga moves forward because the horse pulls forward slightly harder on the wagon than the wagon pulls backward on the horse.
  • B
    Because action always equals reaction, the horse cannot pull the wagon. The wagon pull backward just as hard as the horse pulls forward, there is no motion.
  • ✓
    The horse's force on the wagon is as strong as the force of the wagon on the horse.
  • D
    The horse can pull the wagon forward only if it weighs more than the wagon.
✓

Answer

Correct option: C.
The horse's force on the wagon is as strong as the force of the wagon on the horse.
c
