(adsbygoogle = window.adsbygoogle || []).push({}); I had some trouble with this question, but I would like to know if for these type of questions, is it safe to say that the velocity of a particle/object is equal to: DaVinci said:What is the speed of an objects whose mass is three times its rest mass.

[tex]v=\sqrt{\mid\frac{{m_0}^2}{{X_{m_0}}^2}-1\mid c^2[/tex]

Where [tex]X[/tex] is equal to how many times larger it's relativistic mass is compared to it's rest mass.

??? just curious...

PS: \mid represents absolute value, but I think it would also work if:

[tex]v=\sqrt {-(\frac{{m_0}^2}{{X_{m_0}}^2}-1)c^2}[/tex]
