Shoot the professor and his useless information!:rolleyes: Once again, thanks for the help. I can see that this is going to be a long semester, and I'll be back for sure, lol. Regards, Matt P

Didn't I say that before?

ok... The problem states the is a static friction of 0.4 and a kinetic friction of 0.2. So there is something pushing the cart (a person maybe). BUt if the cart isn't moving, the forces exerted (from the person) are equal to the frictional forces. My total frictional force is 0.6 then?

[/URL] I knew that this wasn't the correct diagram, because the plane was flying horizontally. I take it this one should look like this: http://i7.photobucket.com/albums/y261/daddymattp/hw2.jpg That's good to know. Still not registering here.:confused: So zero kinetic friction force...

I have a diagram of this. It's a block sitting on an inclined plane: Let me try to word diagram this one: pushing left force ---> =has to equal= <--- pushing force left no pushing force = 0 static friction [strong force =/= weaker force] = the cart moves force of cart moving right is...

one piece of a 500 piece puzzle and you don't have a picture to put it together with.

The .4 static friction is greater than that .2 kinetic friction, so static friction is acting on the cart.

No. No I can not. It doesn't look like there is anything pushing the cart.

Ok, so is this question like an essay question then? As in: There is a static friction force acting on the cart. The plane is moving at a constant speed, and the only force action on the cart is gravity keeping it in place.

Sure there is a way to check it! I just don't know what it is.:-p I trust the work is accurate. Thank you for staying up with me until 5AM for some homework that you could have probably done in 20 minutes. If you have the time, could you check my reasoning on this problem as well...

that makes sense. So final answer to the problem is: \mu = .0637
