26.9 Relativistic Energy

Determine the ratio of an electron's total energy to rest energy when moving at the following speeds. $\left(\text{a}\right)\text{ 300m/s,}\left(\text{b}\right)\text{3}\text{.0}\times {\text{10}}^{\text{6}}\text{m/s,}\left(\text{c}\right)\text{3}\text{.0}\times {\text{10}}^{\text{7}}\text{m/s,}\left(\text{d}\right)\text{1}\text{.0}\times {\text{10}}^{\text{8}}\text{m/s,}\left(\text{e}\right)\text{ 2}\text{.0 }\times {\text{10}}^{\text{8}}\text{m/s, and }\left(\text{f}\right)\text{2}\text{.9}\times {\text{10}}^{\text{8}}\text{m/s}$.
