An unstable high energy particle is created in the laboratory, and it moves at a speed of 0.968c. Relative to a stationary reference frame fixed to the laboratory, the particle travels a distance of 1.04 x 10-3 meter before disintegrating.
(a) Calculate what is the proper distance traveled?
m
(b) Find the distance measured by a hypothetical person traveling with the particle?
m
(c) Calculate what is the proper lifetime?
s
(d) Calculate what is the dilated lifetime?
s
