Wow, thanks. I've been trying to plug complex numbers into a matrix for an hour, lol. I know it's possible via rref() but cSolve() is nice and clean.

Perhaps write equations for both of their positions as a function of time and then set them equal to one another to find when they'll collide. From there you can find their velocities.

You're not going to get full use out of computational software without a full understanding of the computations. Just as one won't get much use out of a Russian thesaurus unless they speak Russian. Ti ponemaesh?

Look up the arctan function (also called inverse tangent) and its uses.

My peers and I don't generally use the phrase "limiting friction" so I can't be 100% sure that I know what you mean, but if by "limiting friction" you mean the maximum amount of frictional force that a body/surface allows before they begin to slip, then yes, "maximum static friction means...

They aren't opposing one another. Let's stick to this car example: You would first find the car's maximum static frictional force (the normal force * the static friction coefficient). This value will tell you the maximum amount of frictional force between the tires and the road that can be...

Well, in the scenario you're describing, the frictional force is the centripetal force. This may help:

Well, if the angle between the normal force and the surface upon which the body is traveling is 90 degrees, then I think all you would need to do is make sure that the magnitude of centripetal force doesn't exceed the magnitude of maximum static force between the body/surface. If it does, that...

I should also mention, "centripetal" simply means "center seeking" and applies to the force or acceleration directed towards the center of a circle or arc as an object moves around it in uniform circular motion. The centripetal force could be actualized in many ways, such as in the form of...

Centripetal force is calculated with the following formula: [PLAIN]http://www4d.wolframalpha.com/Calculate/MSP/MSP13719ch7a8fegb1ibfe0000305fb7476a23789e?MSPStoreType=image/gif&s=40&w=168&h=181

I'm assuming you would black out pretty quickly and if the acceleration was sustained for a while I imagine you'd be lucky to survive with brain damage.

As a body moves in a circle at a constant speed, it is said to be in uniform circular motion. You can apply this concept to the space station scenario with the formula for centripetal acceleration in regards to uniform circular motion which is as...

I was saying that I can calculate the area based on the integrand you provided, but was having trouble deducing that integrand myself. Anyways, thanks for your help.

I left out the curve in the first quadrant purposely because it didn't effect my shaded region in the 3rd/4th quadrants. I guess it is safe to assume that the area I've shaded is incorrect, right? I can do the problem pretty easily now on paper but I'm confusing myself a little by trying to...
