Question

The average lifespan (lifespan) of a muon at rest is 2.2 × 10−6 s. Thetime
muon lifeobserved in laboratory measurements was 6.6 × 10−6 s.
Find:
(a) The effective mass of the muon with the velocity it has when the rest mass
is 207 me,
(b) the kinetic energy of the muon, and
(c) the momentum of the muon.

Exercise 1: The mean life-time of muons at
rest is 2.2 x 10-6 s. The observed mean
lifetime of muons as measured in the
laboratory is 6.6 x 10-s. Find (a) The effective
mass of a muon at this speed when its rest
mass is 207 me (b) its kinetic energy (c) its
momentum
