The average energy \(E\) (in kcal) needed for a lizard to walk or run a distance of 1 km has been modeled by the equation
\[E(m, v) = 2.65m^{0.66} + \frac{3.5m^{0.75}}{v}\]
where \(m\) is the body mass of the lizard (in grams) and \(v\) is its speed (in km/h).
Calculate \(E_m(400, 8)\) and \(E_v(400, 8)\) and interpret your answers.
