Using the formula:

v = u + at

where:

v = final velocity (what we want to find)

u = initial velocity (since the plane is at rest, u = 0)

a = acceleration (0.82 m/s²)

t = time (8 seconds)

Substituting the given values:

v = 0 + (0.82 m/s²)(8 s)

v = 6.56 m/s

Therefore, the final velocity of the plane is 6.56 m/s after 8 seconds.
