80c$. We are given that $t = 4.3 \times 10^{-8}$ s. The time dilation formula is given by: $t = \frac{t_0}{\sqrt{1 - \frac{v^2}{c^2}}}$ where $c$ is the speed of light. Show more…

A radioactive particle has a half life of 4.3 microseconds when it is at rest. What will be its measured half life if it is moving at a speed of 2.4 x 108 m/s. Write your answer in terms of microseconds.

A subatomic particle when moving at 0.90c was observed to have a lifetime of 4.1 x 10-6 s. How long would it exist when at rest? 9.4 x 10-6 s 1.3 x 10-6 s 4.6 x 10-6 s 1.1 x 10-6 s 1.8 x 10-6 s

A beam of radioactive particles is measured as it shoots through the laboratory. It is found that, on the average, each particle "lives" for a time of $2.0 \times 10^{-8} \mathrm{~s}$; after that time, the particle changes to a new form. When at rest in the laboratory, the same particles "live" $0.75 \times 10^{-8} \mathrm{~s}$ on the average. How fast are the particles in the beam moving?
