What the does "u" stand for in your equation?

What does N in your equation stand for? Just normal force? Also, If the magnitude of the external net force is 0, That makes the acceleration also 0 correct because Fnet= Ma 0= 0.3 x a 0 divided by 0.3 = 0. That makes them both zero.

A little but I just calculated each of those and subtracted. It comes to zero. Can you please tell me how you got those formulas?

Tension? But I don't know how to calculate it.

Okay I drew it. FBD of hanging object only has Fg and Ft The one on the table has FN, Fg and Ft. ?

The forces acting on a chain are Fg, Fn, Ft and Ff, why? How can Fnet= ma help?

Damn, I guess I'll have to wait a little bit longer for someone to reply that knows what they're doing.

Homework Statement A heavy metal chain of mass 0.6 kg hangs over the edge of a table. When half the chain is hanging over the edge, what is the magnitude of the external net force that causes the chain to accelerate? What's the acceleration of the chain when half of it is over the edge?Homework...

If i answer it, can you verify if it's correct or not. For 1, I'm pretty sure It's E, N30E because the line of that one is connected to S30W. For #2, I think the answer is D (N20W) because it looks opposite.

i have an idea of it but I don't get these. mind answering them? itll give me a better understanding.

Homework Statement Which of the following vectors are collinear with S30W? a N60W b S30E c W30N d E30S e N30E Which of these vectors are perpendicular to E20S? aN20E W20S W70S N20W E70N How do you know if they're collinear and how do you know if their perpendicular...

Thank you so much.

Okay, If I can use vector addiction, than I can do it the way I mentioned earlier by making a triangle and finding the unknown side and angle because they both are ways of finding the same thing. correct?

What? I just need to know what formula to use or how I can use my graph to find the answer. I'm given the planes Velocity (100m/s n20e) and than the wind (40 m/s s10e)

Homework Statement An airplane is flying 100m/s (N20E) according to the pilot, but is in a wind that is blowing 40 m/s (S10E). What is the plane's real velocity? Homework Equations Pythagorean Therom Cosin and Sin Laws Component Method The Attempt at a Solution Okay, I think I...
