The acceleration of the object described above is calculated by dividing the given initial velocity by the time it took for it to completely stop. That is,
a = Vi / t
Substituting the known values,
a = (34 m/s) / 6 s = 5.67 m/s²
The answer to this item is -5.67 m/s² because the motion of the object is that it is coming to a full stop from high velocity motion.
