A muon is a subatomic particle with a mass of 1.88x10-28 kg that can be found in cosmic rays. A certainmuon travels 60 km through earth’s atmosphere in 210 micro-secosnds as measured by an experimenter on the ground.

a. What is the speed of the muon in km/s and as a fraction of c?

b. How long does the journey take according to the muon?

c. What is the Newtonian momentum of the muon?

d. What is the relativistic momentum of the muon?

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,...

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...

A cosmic ray muon with mass mμ = 1.88 ✕ 10−28 kg impacting the Earth's atmosphere slows down in proportion to the amount of matter it passes through. One such particle, initially traveling at 2.42 ✕ 106 m/s in a straight line, decreases in speed to 1.52 ✕ 106 m/s over a distance of 1.30 km. (a) What is the magnitude of the force experienced by the muon? N (b) How does this force compare to the weight of the...

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 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...

A muon is an elementary particle that resembles a heavy electron. It has a rest mass of 105.7 MeV/c2 compared to the electron rest mass of 0.511 MeV/c2. In frame, S, the muon has a velocity of   0.85 c ms?1 . In frame, S', the muon is found to have a velocity of     0.65 c ms?1 . The muon velocity vectors in either frame and the velocity of relative motion of frame S and S' are all parallel to the...

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...
