A neutral $\pi$ -meson is a particle that can be created by accelerator beams. If one such particle lives $1.40 \times 10^{-16} \mathrm{s}$ as measured in the laboratory, and $0.840 \times 10^{-16} \mathrm{s}$ when at rest relative to an observer, what is its velocity relative to the laboratory?
$v=0.800 c$

the life of the bind his own when it rest relative to an observer. Proper time Delta T not is equal to 0.8 for zero multiplied by 10 to the power minus 16 seconds. And the life of the crime is own When measured in the liberate ary, a Delta T is equal to one point for zero. Multiply by 10 to the power minus 16 seconds, and their latest ick factor is given by one divided by spare route off one minus We divided by sea Whole square. Well, we know that are from time dilation. Delta T is equal to don't 30 not divided by square root off one minus. We divided by sea hold spare and this can be for the returnees we is equal to you could be solved. For we we is equal to see Time's C is the speed of flight. See Time's square root off one minus Delta T not Delta t not divided by Delta T Old scare. Now let's look in the values we is equal to see into spare route off one minus. Well, I don't Did he not Delta T naughty zero point 840 multiply by 10 $30 minus 16 Divided by delta, T and l titties. One point for zero multiply. I tend to devour minus 16 and then we have a scale as well. And solving this we get we is equal to 0.800 times the speed off light.
