${v}_{f} = - 11.96$ $m \text{/} s$

#### Explanation:

First we can write out the given information:
${v}_{i} = 0$ $m \text{/} s$
$\Delta t = 2.6$ $\sec$
$a = - 4.6$ $m \text{/} {s}^{2}$

Since we are looking for ${v}_{f}$, we can use the equation:
${v}_{f} = {v}_{i} + a \Delta t$

Plugging in the given values, we get:
${v}_{f} = 0 + \left(- 4.6\right) \left(2.6\right) = - 11.96$ $m \text{/} s$
