If your reference is attached to m, than that means you see the particle M traveling with kinetic energy 1/2Mv^2 while particle m has zero velocity, relative to M. If you were attached to M, than you would see the opposite. You would see kinetic energy 1/2mv^2. It's all relative brotha. I think...

Or in a different sense. Einstein's theory of special relativity begins on the determination of synchronous events. He does so by introducing a thought experiment suggesting that if a beam of light is sent from position A to position B and reflected back again, while another beam of light is...

Sorry about all the confusion. Let me try one more approach. If you are in a car and you slam on the brakes, your body tends to be pushed forward. When you analyze this situation from your point of view, you find that your motion forward is caused by no apparent force. This is called a...

The convective acceleration can be converted from a non-inertial FoR to an inertial one. If the analysis is to be done in an inertial FoR, than the force caused by convective acceleration would be replaced by an equivalent force as seen from that reference point. So to completely answer your...

Before I get reamed for this by an architect, I must say that this is purely speculation and that I have no experience in the field of architecture, so take this lightly. But I believe that this is the general procedure. Architects propose (by means of a drawing) the aesthetics of a building...

The Navier Stokes equations is the application of Newton's second law to a fluid. Basically, it is the conservation of momentum. The NS equations can be written for an inertial reference frame: rho*(dv/dt+v*grad(v)) = -grad(P)+grad(T)+f the terms on the LHS represent the inertial and...

The Reynolds transport theorem is the derivative of a blob of fluid taken along a path which is moving with a certain velocity. I can present an analogy. If a plane is flying over a country side, that plane is said to be in a inertial frame with respect to an observer on the ground. The blob of...

First of all, thanks CompuChip, I'm getting closer at an answer. This is what I've come up with so far: P(1st digit not being 1 or 2) = 7/9 P(2nd digit not being 0,1 or 2) = 7/10 P(3rd '' '' '' '' ) = 7/10 . . ...

Homework Statement Let k >= 3 be any integer. What is the probability that a random k-digit number will have at least one 0, one 1 and one 2? (as usual every number starts with either 1,2,...9 and NOT zero) Homework Equations b(x : n,p) = (n x)p^x*(1-p)^(n-x) where x = 0, 1, 2, ... ,n...

There is a rather long, but simple derivation of the mean kinetic energy of a particle related to temperature (see http://en.wikipedia.org/wiki/Kinetic_theory). As you can see, your professor made a mistake and it is indeed (3/2)KT. Take into account however, that this is only applicable for an...

Hey, this is stealthxxy (apparently there were a few mix ups due to multiple accounts, sorry about the inconvenience). Jarednjames, let me be more specific. I have already sketched multiple aircraft for specific design requirements. From these requirements, I calculated wetted areas, reference...
