Homework Statement
A 14C nucleus, initially at rest, emits a beta particle. The beta particle is an electron with 127 keV of kinetic energy.
A) What is the speed of the beta particle?
B) What is the momentum of the beta particle?
C) What is the momentum of the nucleus after it emits...
I'm pretty sure this isn't right, but this is what I tentatively have down:
The two groups in the first year did not differ at all. “In the experimental year, the degree of synchronization did not differ between food-supplemented and control females.” The t statistic -1.05 is a two-sample...

Do birds learn to time their breeding? Blue titmice eat caterpillars. The birds would like lots of caterpillars around when they have young to feed, but they breed earlier than peak caterpillar season. Do the birds learn from one year's experience when they time...
Oh that algebra works. Darn that distributing the v! That's the part that was confusing me (not including the rest of the problem haha) Thanks for clearing up the algebra though. And yes, your answer is right.
Okay, can we come at this from another angle?
On another site, someone has posted this as the work for the problem (and the answer is right). Can you tell me how they figured out a step? I feel as if it seems easier than everything you all have been doing (no offense, and hell, it might be...
If I were to do it this way, how do I isolate v?
v=xSQRT(1-v2/c2)/t0
I've tried to get v down to one side, but I'm stuck. Or was I supposed to set x/t=xSQRT(1-v2/c2)/t0
This stuff is just confusing to me, and I'm not really clear on what the other Royal was getting at, so I'm coming...
Okay, wow, yeah, I must have been kind of out of it haha.
So if I use time dilation, t=t0/(SQRT(1-v2/c2))
Is the lifetime of the particle at rest t0? If so, how do I find the other time? If not, how do I find either? Thanks!
Looking back on the work I did, I'm naive. I know that in this problem I should use either t=t0/(SQRT(1-v2/c2))
OR
L=L0*(SQRT(1-v2/c2))
But I'm not sure which (or both?)

Faraway Point starbase launches a probe toward the starships approaching from the same direction. The probe has a velocity relative to the Picard of -0.895c. The Picard approaches starbase Faraway Point with a speed of 0.795c, and the La Forge approaches the starbase with a...

When at rest, the Sigma- particle has a lifetime of 0.15 ns before it decays into a neutron and a pion. One particular Sigma- particle is observed to travel 3.2 cm in the lab before decaying.
What was its speed? (Hint: Its speed was not 2/3 c)
