Posted 2003-10-01, 10:36 AM in reply to Titusfied's post "Another Probability Riddle No One Will..."
I only looked at one case (x = 30) which results in a 58 1/3% chance so I would assume Grav's answer is accurate. I would actually try to answer this, but I've got some physics to work on...

However, due to Titus's outbreak:

Then I would be able to answer them.
I'll post a few of simpler problems from Chapter 37 Sections 4-6 and 8 (Simultaneity, Time Dilation and the Twin Paradox, Length Contraction, and Galilean and Lorentz Transformations, respectively) from my PHYS 1444 class.

1) A certain type of elementary particle travels at a speed of
2.70x10^8 m/s. At this speed, the average lifetime is measured to be 4.76x10^-6 s. What is the particle's lifetime at rest?

2) A certain star is 95.0 light-years away. How long would it take a spacecraft traveling .960c to reach that star from Earth, as measured by observers: (a) on Earth, (b) on the spacecraft? (c) What is the distance traveled according to observers on the spacecraft? (d) What will the spacecraft occupants compute their speed to be from the results of (b) and (c)?

3) A farm boy studying physics believes that he can fit a 13.0m long pole into a 10.0m long barn if he runs fast enough, carrying the pole. Can he do it? Explain in detail. How does this fit with the idea that when he is running the barn looks even shorter than 10.0m?
