A particle detector can be used to measure the speed of an unstable particle if the lifetime is known. Particle 'X' has mean lifetime 7 in its rest frame. Suppose 'X' particles are created in an experiment inside the detector by a nuclear reaction. If the 'X' particles leave tracks with mean length L before they decay into other particles, what is the mean speed of the 'X' particles? Express the answer in terms of the speed of light.

Particle-X has a speed of 0.730 c and a momentum of 6.240×10-19 kgm/s. What is the mass of the particle? Hints: The classical momentum of an object is the product of its mass and its velocity. How does the relativistic momentum look like compared to the classical momentum? What is the rest energy of the particle? Hint: This is THE very famous relationship between mass and energy attributed to Einstein. What is the kinetic energy of the particle? What is the total energy of the particle?

A particle has a mass of 1.88E-28 kg and it travels at a speed of 0.969c, where c is the speed of light. What is the energy of the particle, expressed in MeV. Keep three significant digits.
Compute the kinetic energy of a proton (mass 1.67 x 10-27 kg) using both the nonrelativistic and relativistic expressions, and compute the ratio of the two results (relativistic divided by nonrelativistic) for speeds of (a) 8.00 x 107 m/s and (b) 2.85 x 108 m/s
The factor γ appears in many relativistic expressions. A value γ = 1.01 implies that relativity changes the Newtonian values by approximately 1% and that relativistic effects can no longer be ignored. At what kinetic energy, in MeV, is γ = 1.01 for (a) an electron, and (b) a proton?
A tau lepton is a particle that decays into a muon and two particles of negligible mass. The tau lepton has a rest mass energy of 1777 MeV, and the muon has a rest mass energy of 105.7 MeV. Suppose the tau lepton is at rest and all of the missing mass goes into the muon's kinetic energy. How fast will the muon move? (Enter your answer in terms of c to at least four significant figures.)
A photon decays into an electron-positron pair. What is the kinetic energy of the electron if its speed is 0.900c?
special relativity As a result of the collisions of cosmic rays with atoms in the upper atmosphere, muon particles are produced kilometers above the Earth's surface. The muon is an unstable particle with a half-life of 1.5 µs. In an experiment, a measurement is made with a muon detector in a balloon 2000 m above the ground, and 650 muons are observed in 1 hour, each of which has a speed of 0.99c in the direction of the Earth. How many of these muons are observed in 1 hour at sea level? (Use No/2^n muons left at the end of the half-life from the No number of muons at the beginning. )
What is the momentum in MeV/c of an electron with a kinetic energy of 2.00 MeV?
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!!
Particles accelerators such as the Large Hadron Collider (LHC) can accelerate particles up to tremendous energies. Suppose the LHC accelerates alpha particles (a.k.a. helium nuclei with a charge of +2e and a mass of 6.645 x 10-27 kg) with a kinetic energy of 7.5 TeV*, what would the speed of one particle be if relativistic effects** are ignored? Give your answer in units of Gm/s. *T as in Tera, for 1012. "eV" stands for "electron volt," which is a non-Sl unit of energy equal to what one electron would gain after travelling through 1V. 1eV = 1.602 x 10-19 J. **Special relativity is necessary to correctly account for the limiting speed of light, which is about 3 x 10° m/s. Note that in ignoring this effect and applying Newtonian mechanics (what you learned in Phys1210 or equivalent), you'll be getting a speed way above 0.3 Gm/s. That's just how insanely energetic the LHC is.
The dimensionless parameter γ is used frequently in relativity. As γ becomes larger and larger than 1, it means relativistic effects are becoming more and more important. A. What is γ if v = 0.28c? B. What is γ if v = 0.53c?
