Calculate the aceleration of a vehicle wich start with a zero meter per second, and acelerates to 34 m/s in 21 s. HELP PLSSS

For the aceleration we have:

Vf = Vo + a * t

Clearing "a":

a = (Vf - Vo) / t

Replacing and resolving:

a = (34 m/s - 0 m/s) / 21 s

a = 34 m/s / 21 s

a = 1,61 m/s^2

The aceleration of the vehicle is 1,61 meters per second squared
