In perfectly inelastic collision of fast moving proton with the similar target particle, the energy available to create a product particle is given by M c 2 = 2 m p c 2 1 + K 2 m P c 2

Question

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.)

Consider the inelastic collision. Two lumps of matter are moving directly toward each other. Each lump has a mass of 0.500 kgand is moving at a speed of 0.910?. The two lumps collide and stick together. Answer the questions, keeping in mind that relativistic effects cannot be neglected in this case. What is the final speed ?f of the combined lump, expressed as a fraction of ?? ?f= ? What is the final mass ?f of the combined lump immediately after the collision, assuming that there has not yet been significant energy loss due to radiation or fragmentation? ?f=

One of the many fundamental particles in nature is the muon μ. This particle acts very much like a "heavy electron." It has a mass of 106 MeV/c².compared to the electron's mass of just 0.511 MeV/c². (We are using E=mc² 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 neutrinos (V). We'll ignore the neutrinos throughout this problem. If the muon is at rest, the characteristic time that it takes it to decay is about 2.2 μs (Tμ = 2.2 × 10 s). Most of the time, though, particles such as muons are not at rest and, if they are moving relativistically, their lifetimes are increased by time dilation. In this problem we will explore some of these relativistic effects. Figure Earth μ 27 Proton A stream of particles, often called cosmic rays, is constantly raining down on the earth from outer space.
