You are a passenger on a jetliner that is flying at constant velocity. You get up from your seat and walk toward the front of the plane. Because of this action, your forward momentum increases. What happens to the forward momentum of the plane itself?

A) It decreases.

B) It increases

C) It remains constant.

option (A)

Explanation:

The momentum of the plane remains constant.

As according to the Newton's second law, the rate of change of momentum of the body is directly proportional to the force applied on the body.

As there is no force, so the momentum of the plane is conserved.

As your forward momentum increases, so the forward momentum of the plane decreases.

Option (A)
