A muon is an unstable particle whose mean lifetime is 2.2 ∙ 10-6 s as measured by an observer at rest relative to the muon. A large burst of such muons is produced 6.0 km above the ground level, after which the muons move towards the surface of the Earth with a velocity 0.92?. a) What is the mean lifetime of the muons to a stationary observer on the surface of the Earth? b) What percentage of the muons reach the surface of the Earth?

Muons are unstable subatomic particles that decay to electrons with a mean lifetime of 2.2 μs . They are produced when cosmic rays bombard the upper atmosphere about 11.1 km above the earth's surface, and they travel very close to the speed of light. The problem we want to address is why we see any of them at the earth's surface. A. What is the greatest distance a muon could travel during its 2.2 μs lifetime? B. According to your...

Muons are unstable subatomic particles that decay with a mean lifetime of 2.197us (producing electrons and neutrinos) as measured in the inertial frame of the muons. Many are produced in the upper atmosphere about 10 km above the surface of the Earth, and some of them travel very near the speed of light on their way to the surface. A) Calculate the largest distance any particle can travel in 2.197us, with both the time and the distance measured by observers...

A muon is a type of unstable subatomic particle. When high-speed particles from outer space (sometimes called "cosmic rays") collide with atoms in the upper atmosphere, they can create muons which travel toward the Earth. Suppose a muon created in the atmosphere travels at a speed of 0.941c toward the Earth's surface for a distance of 3.48 km, as measured by a stationary observer on Earth, before decaying into other particles. (a) As measured by the stationary observer on Earth,...

A pion is an unstable particle which decays into a muon (which is also unstable and further decays into an electron). The pion’s average lifetime when it is at rest is 26 ns. If the pion moves with a speed of 0.9819 c, what is (a) its average lifetime (ns) as measured by an observer on Earth and (b) the average distance (m) it travels before decaying as measured by an observer on Earth? (c) What average distance (m) would...

A muon formed high in Earth's atmosphere travels towards Earth at a speed v = 0.970c for a distance of 4.30 km as measured by an observer at rest with respect to Earth. It then decays into an electron, a neutrino, and an antineutrino. (a) How long does the muon survive according to an observer at rest on Earth? (b) Compute the gamma factor associated with the muon. (c) How much time passes according to an observer traveling with the...

6. The muon particle was a bit of a strange case until relativity came along. The muon forms 1.0 × 104m above the surface of the Earth and speeds downwards at 0.998c. From the particle’s perspective, it has a lifetime of 2.2 × 10−6 s. a) Use classical physics to determine how far the muon should be able to travel in its lifetime. b) This travel distance was puzzling since the muon was observed in great numbers at Earth’s surface....

Muons are elementary particles with a small mass. They are often created in the atmosphere by cosmic ray collisions. Once the muon is created, its lifetime is only 2 microseconds (2×10−6 seconds). A typical velocity is 0.9999 c, just 0.1 % below the speed of light. Without relativity, the muons would only travel 600 meters before decaying, yet we see muons created 10 km in the air reach our instruments on the ground. a) Consider a muon created 10km above...

One of the many fundamental particles in nature is the muon mu. This particle acts very much like a "heavy electron." It has a mass of 106 MeV/c^2, compared to the electron's mass of just 0.511 MeV/c^2. (We are using E = mc^2 to obtain the mass in units of energy and the speed of light c). Unlike the electron, though, the muon has a finite lifetime, after which it decays into an electron and two very light particles called...

A particle has rest energy 1872 MeV and mean lifetime 8.2 × 10−11 s. It is created and decays in a particle track detector. It leaves a track 35 mm long. (a) What is the (i) speed of the particle in terms of c? (ii) momentum of the particle? (b) How much energy is needed to produce the particle? (c) Is the particle massless? Justify your answer.
