15. A 100-kg man hits a punching bag with a net force of 2,000 N, as his hand accelerates from 0 m/s to 20 m/s in 1 s. With how much force does the punching bag hit the man?

The force exerted by the punching bag on the man is 2000 N

Explanation:

We can answer this question by applying Newton's third law of motion, which states that:

"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"

In this problem, we can identify:

  • The man as object A
  • The punching bag as object B

As a result, we have:

  • The force exerted by the man on the punching bag (2000 N) is the action
  • The force exerted by the punching man on the man is the reaction

According to Newton's third law, action and reaction have equal magnitude: therefore, the force exerted by the punching bag on the man is also 2000 N (in the opposite direction).
