Hey guys, this is going to be a bit long but please bear with me. I'll start off with how everything started. I've always wanted to do engineering. My dad is a chief engineer of a merchant vessel and growing up, I guess it brushed off on me. I was fairly decent in high school. I gradded...

Ahh, we refer to every force as this: Fn would be Normal Force Ff would be Force of friction Fg would be Force of gravity Fa would be Applied Force Those Fn, Ff, Fg and Fa are on the diagram. Those are my forces.

What's uN? We haven't been taught that yet. I'll check the vertical and horizontal thing. Thanks.

I was speaking in general and not keeping f(x) in mind regarding the variables being 1. What I'm trying to say is consider this equation: x + 5. If we were to re-write that in another way, it can be 1x + 5. x isn't defined with 1, what I meant to say is explained in that equation. Maybe I said...

Yes, I know it's a function. Maybe the way we learned things is different. Also, for the 2nd part, if you had to say what x was without it being defined at all, what would you say? As far as I know, when it's only a variable (be it x, a, b etc.), we take it as 1.

I'm taking it as a 0 because he didn't specify any other number. If he had specified 1, 2, 3, 4 etc. then I have would've used that. When I was doing this in my homework, an exact question I came upon was y = f(x) - 6 and we had to assume that f(x) = 0 since f(x) wasn't defined. It's like...

Exactly. But, since he didn't specify what f(x) is, I took it as 0 as well and ended up with y = -4. Wouldn't that work then?

In a graphing calculator, you should graph this cristo: y = f(x) - 4 and you will get a straight line 4 units down. It's going to be a horizontal line and the coordinates would be: (0,-4). I tried it and that's what I got. Maybe I did it wrong but I'm not completely sure about it.

I think ZioX is right. From what I remember, f(x) is the same thing as y so it's saying (IMO): y = -4. So it would be shifted down 4 units and you should have a horizontal line.

You have to show your work :). If somebody sees that you've at least tried to attempt it, they will surely help you. I can too, but need show you've attempted it at least. :)

Hello, I have this Physics problem that's due tomorrow in class and I'm having some troubles with it. Homework Statement PROBLEM: A racing car has a mass of 1500kg is accelerating at 5.0m/s^2, is experiencing a life force of 600N up (due to its streamlined shape) and group effects of 1000N...
