I'm honestly trying to do it but since my math isn't that strong and I've never seen a problem like this I'm just having problems. Can you do the first step for me or walk me through a bit more step-by-step? I'm just having extreme difficulty

I kind of understand what you're saying, but not really. I don't even think I understand what the question is asking to be honest. I don't understand how there can be x and y but also i and j coordinate systems.

Homework Statement A force acts on a particle and is given by the following expression: F(x,y)=2x^3 y^2 i+3xy^3 j What is the work done by this force in moving the particle from a position (x,y) = (0,0) to (4,2) along the path given by the curve y=√x ? Homework Equations I know...

No, it's fine. I was just wondering I guess. Thank you :)

Homework Statement Homework Equations W = fdcos∅ The Attempt at a Solution I know how to solve the problem using potential energy (i.e. mgh) and the answer is 4.41 J. My question is, how do I solve it using the work done by the applied force using fdcos∅? The work done...

Oh wow, thank you very much! I get it now

Alright, I don't have a specific homework problem here, just a general question. I've attached two pages that I will be referencing. Figure 1. Inclined Plane As can be seen here, the FN = mgcos(∅) Figure 2. Banked Curve It seems as if the opposite is true here. FNcos(∅) = mg...

Homework Statement http://i.imgur.com/rjxR2.jpg Homework Equations F = ma The Attempt at a Solution I know that the rope is pulling the man up twice as much because there are two points of contact between him and the rope. I'm really just looking for somebody to explain why that...

There's just something I need cleared up. When rotating around a line that isn't the x or y axis,I'm not quite sure what to do. Here are some problems: 1) Find the volume of the solid that results when the region enclosed by y=√x, y=0, and x=9 is revolved around the line x=9. 2) Find the...

I'm honestly lost. Any way you can write out the steps a bit and I'll follow (not much explanation is necessary, as I kind of understand).

Homework Statement A block of mass 4.0 kg is put on top of a block of mass M = 6.0 kg. To cause the top block to slip on the bottom one, while the bottom one is held fixed, a horizontal force of at least 19 N must be applied to the top block. The assembly of blocks is now placed on a...
