Ahh sweet, that's cleared things up a little - many thanks!

I can't isolate the p^{2} term. When I take the treat the integrand as an exponential to a complex power, I wind up with e^{-\frac{(p^{2}-2pp_{0}+p_{0}^{2})}{\sigma}+\frac{ix}{\hbar}p}

Homework Statement \Psi(x,t) = \int^{\infty}_{-\infty} C(p)\Psi_{p}(x,t) dp is a solution to the Schroedinger equation for a free particle, where \Psi_{p}(x,t) = Ae^{i(px-Ept)/\hbar}. For the case C(p) = e^{-(p-p_{0})^{2}/\sigma} where \sigma is a real constant, compute the wavefunction...

0.357c. And v isn't great enough for the length contraction to be the part I messed up on.

Homework Statement Two spaceships are moving away from Earth at a speed of 0.8c, with one ship following in the flight path of the other. Their separation along the axis of their motion is maintained at 0.1 light years as measures by the spaceships' instruments. A crew exchange vehicle is...

Ha, it didn't occur to me ct was in meters (very new to SR). Thanks!

I'm currently completing a special relativity assignment, and whenever coordinates are referred to they're represented as (x1, ct1) = (25m, 25m) or (6m, 2m). There are no units given (other than the 'm', and I highly doubt they're using minutes for ct). If someone could clear this up for me I'd...

Yes I can, thankyou very much for your help!

I've tried it, I can factorise the numerator (x+y)(x-y), but I can't factorise the demoninator, and don't see any available substitutions

Thanks for the reply, but for this problem I don't think that site will help me very much, as I don't have a problem tackling any of the four problems it poses (the first two are just simple substitutions, and the second two just require the Two Path Test to demonstrate that no limit is...

Hello, I've been trying to solve the following limit for the last hour or so. I'm pretty much at a loss as to how to solve it (I need to do a lot of these kinds of problems, but I need to understand how to approach them first), so any pointers in the right direction would be appreciated...

Thankyou very much!

I was given this as a practice question, and assumed that the answer would be 0. The answer is e, but no explanation is given and I cannot figure out why this is. z is undefined in the question. If anyone could shed some light it would be greatly appreciated.

For my physics major I'm required to take a broadening unit each semester. I've decided I'll learn a language, I'm thinking either German or Japanese (although I would welcome other suggestions). I would be just as happy to learn either language, so I thought I'd pose the question as to which...

If one of the reactors at Fukushima underwent a full meltdown, how devastating an effect would it have on the region?
