What is Newton’s second law of motion?
If you have an object with a mass that is accelerating that is equal to amount of force applied to the object. F=MA
It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

What is 100km/2hr= 50km/hr?
Many students chose this option “The air is pushing on the sail, but the sail is not pushing on the air.” Explain why this answer is incorrect.
Because as the sail applies force to the air too, the air will push back with the same amount of force, now depending on their mass, it will determine which object moves towards the opposite direction.
What are two?
