3.9. A particle is traveling at 3c in the x direction. Determine its proper velocity, n (all
four components).
2.9. (a) Solve the integral
...| (dx .dx3N)
3N
and use it to determine the "volume"
the relevant region of the phase space of an extreme
relativistic gas ( = pc) of 3N particles moving in one dimension. Determine, as well, the
number of ways of distributing a given energy E among this system of particles and show that,
asymptotically, w0 = h³N.
(b) Compare the thermodynamics of this system with that of the system considered in Problem 2.8.
Suppose that the speed of light in a vacuum ( c), instead of being a whopping 3×108m/s, was a rather sluggish 40.0mph. How would that affect everyday life? Throughout this problem we are going to assume that c=40.0mph and that time dilation is in full effect. Let's start by assuming that it is fairly easy to accelerate to speeds close to 40.0mph. We will also ignore gravity throughout this problem. Otherwise, the earth (with an escape velocity of 11km/s11km/s) would have turned into a black hole long ago.
Part A Suppose that a bored student wants to go to a restaurant for lunch, but she only has an hour in which to go, eat, and get back in time for class. Considering that it usually takes about 30 minutes in most restaurants to get served and to eat, what is the farthest restaurant the student can go to without being late for class? Assume in this part that the student has a car that can accelerate to its top speed in a negligible amount of time. Also, the local speed limit is 30 mph…

- A particle has γ=18,399. a) Calculate c-v in m/s. (I would have asked for 1 - v/c, making the answer dimensionless, but the system doesn't seem to take numbers that small. Gamma is chosen to make the particle extremely close to the speed of light.) If your calculator gives problems, you might want to solve the appropriate equation for c-v or c(1 - v/c) and use an approximation. b) In a race to the moon, by 3/4ths the distance, light is one or ten meters ahead of the particle. We routinely approximate mass as zero, gamma as infinite, and speed as the speed of light. ("Massless particles" -- gamma and m have to be eliminated from the expressions. Light is a true massless particle.) If a massless particle has momentum 1,739 MeV/c, calculate its energy in MeV. Thank you so much!!arrow_forwardA particle has γ=18,399. a)Calculate c-v in m/s.

- The Tevatron was a large particle accelerator that would collide beams ofprotons and anti-protons to see what would come out of the collisions.a) Let’s assume that each particle (in both beams) was accelerated to a total energy of100 GeV. What is the speed of the protons (relative to the speed of light) if you assumethe mass of the proton is equal to 1 GeV/c^2? Write your answer in terms of the speed oflight—keep it as a decimal times “c”. You will need several decimal places.b) Suppose that you now accelerate each particle to a speed of 0.9c. Since they are movingin opposite directions, what is the speed that one would measure for the speed of the otherparticle? Just give the absolute value of this speed. Don’t worry about the sign.c) Given your answer in part b, what is the energy of that one particle would measure forthe other particle?arrow_forwardProblem 2: (a) Since the four-velocity u = Yu (c, u) is a four-vector, you should immediately know what its transfor- mation properties are. Write down the standard Lorentz boost for all four components of u. Use these to derive the relativistic velocity transformation formulas. (b) In non-relativistic mechanics, the energy E contains an arbitrary additive constant. That is, no 1 physics is changed by the replacement E → E + Eo for any constant Eo. Using the fact that the four- momentum p = (E/c,p2,Py, Pz) must transform like a four-vector, show that this is NOT true in relativistic mechanics.arrow_forwardA particle has γ=15,687.
