216 m.

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 6 m/s

Acceleration (a) = 2 m/s²

Time (t) = 12 secs

Distance travelled (s) =.?

Next, we shall determine the final velocity of the truck.

This can be obtained as follow:

Initial velocity (u) = 6 m/s

Acceleration (a) = 2 m/s²

Time (t) = 12 secs

Final velocity (v) =?

v = u + at

v = 6 + (2 × 12)

v = 6 + 24

v = 30 m/s

The, the final velocity of the truck is 30 m/s.

Finally, we shall determine the distance travelled by the truck as follow:

Initial velocity (u) = 6 m/s

Final velocity (v) = 30 m/s

Acceleration (a) = 2 m/s²

Distance travelled (s) =.?

v² = u² + 2sa

30² = 6² + (2 × s × 2)

900 = 36 + 4s

Collect like terms

900 – 36 = 4s

864 = 4s

Divide both side by 4

s = 864/4

s = 216 m

Therefore, the distance travelled by the truck is 216 m
