A B+ meson has a speed of xc. It travels y mm in the laboratory before decaying. Calculate the B+ meson’s proper lifetime.
Added by Esther R.
Step 1
We know that the B+ meson has a speed of xc in the laboratory frame. However, we need to express this speed in terms of the speed of light (c) to use it in relativistic calculations. We can do this by dividing the speed of the B+ meson by the speed of light: v = Show more…

An elementary particle produced in a laboratory experiment travels $0.230 \mathrm{~mm}$ through the lab at a relative speed of $0.960 \mathrm{c}$ before it decays (becomes another particle). (a) What is the proper lifetime of the particle? (b) What is the distance the particle travels as measured from its rest frame?
A meson particle when at rest decays 2 μs after it is created. (a) If moving in the laboratory at 0.99c, its lifetime according to laboratory clocks would be what? (b) What distance would the meson travel during its lifetime as measured in the laboratory reference frame?
