$a = 4 \frac{m}{{s}^{2}}$

#### Explanation:

Since acceleration is described as a change in velocity over change in time, then we can do the following

color(white)(-----)color(magenta)(a = (v_(f)-v_(i))/(Deltat)

We know the following

$\Delta t = 2 \text{ s}$
${v}_{i} = 0 \text{ m/s}$
${v}_{f} = 8 \text{ m/s}$

Now, plugin

• color(magenta)(a = (v_(f)-v_(i))/(Deltat)

• $a = \frac{\left(8 \frac{m}{s}\right) - \left(0 \frac{m}{s}\right)}{2 \text{ s}}$

• color(blue)(a = 4 (m)/(s^2)

color(blue)("Answer" = a = 4 (m)/(s^2)#
