In summary, the conversation discusses the relationship between horizontal function, weight, mass, and acceleration due to gravity. The speaker's answers are correct, but their reasoning is incomplete. They mention that a horizontal function implies zero net force, but it is only in the case of a constant drag force that this is true. The special thing about drag force, when combined with Newton's second law, is that it results in a net force of zero. The conversation also notes that the speaker has not answered question 25, but it is said to be easy after answering the first two questions.

My answer: Horizontal function implies zero net force. Therefore, weight is 160 N. Thus, mass is 16 kg such that the acceleration due to gravity is 9.8 N/kg. Am I right?

Your answers are correct but your reasoning is not entirely correct or it is incomplete I would say. The part of the graph where it becomes horizontal doesn't necessarily imply that the net force is zero, however it is implying it in this specific case of drag force being constant. Why? What's the special thing about drag force and how this combined with Newton's second law implies that the net force is zero.

You haven't answer question 25 btw but ok its fairly easy after answering the first two questions.
