Hey,

So if a plane is flying with constant velocity along a horizontal plane that is "level" (W vector is perpendicular) and the acceleration is zero what is the net horizontal force?

I think it is zero because the net force equals mass(acceleration) and the acceleration is zero. Any have any ideas?

[Anon88]

F=m(mass)*a(acceleration)
a=0

so I think F equals 0.

Yes, thank you for your reply. I ended up trying it anyways and got it correct.

I presume we are ignoring drag?

[MrHappy0]

Yup. I am in Physics 051 (fundamentals of physics). We just got into the 5th chapter on free-body diagrams and are ignoring friction and other forces that would complicate the problem. I am sure I will be back once we get there though.

Think the question over. It states "constant velocity", it doesn't say anything about why the velocity is constant.

In other words: it is not only drag that is ignored, as it is irrelevant to the question.

Sorry, I missed the "net" horizontal force in the original question
