We know that

• The initial velocity is zero because it starts from rest.

,

• The acceleration is 8 m/s^2.

,

• The time elapsed is 3 seconds.

Use a formula that relates initial velocity, acceleration, time, and distance.

[tex]d=v_0t+\frac{1}{2}at^2[/tex]

Use the given magnitudes to find d.

[tex]\begin{gathered} d=0\cdot3\sec +\frac{1}{2}\cdot(8\cdot\frac{m}{s^2})(3\sec )^2 \\ d=4\cdot\frac{m}{s^2}\cdot9s^2 \\ d=36m \end{gathered}[/tex]

Therefore, the distance covered is 36 meters.
