Finding Limits: Numerical and Graphical Approaches · Exercise 51

According to the Theory of Relativity, the mass $m$ of a particle depends on its velocity $v$. That is

$$m=\frac{m_o}{\sqrt{1-\left(v^2/c^2\right)}}$$

where $m_o$ is the mass when the particle is at rest and $c$ is the speed of light. Find the limit of the mass, $m,$ as $v$ approaches $c^{-}.$
