Special Relativity: Time Dialation

Speeds typical of our everyday lives results in the laws of Classical Mechanics; however, when a particle approaches a reasonably high fraction of light speed (cc), the time (tobst_\text{obs}) we observe is dilated such that: tobs=t1v2c2 t_{obs} = \frac{t}{\sqrt{1 - \frac{v^2}{c^2}}} In an obscure Prussian lab, a positron's velocity (vv) was accelerated to 0.6c0.6c. If tt, as experienced by the positron, is 200200 femtoseconds\text{femtoseconds}, what would we observe as the dilated time?

Hint: Find tobst_\text{obs} in fs\text{fs}.
