Over a span of 8.0 seconds, an object moves 16 m to the left relative to where it began. if we treat left as the direction towards increasingly negative displacement, what is the average velocity of the object during this motion?

-2 m/sec

Explanation:

We have given time t = 8 sec

As the object move in left relative to where it began and it is increasingly negative direction

So displacement = -16 m

We have to find the velocity

So velocity

As the velocity is a vector quantity so negative sign has significance its the direction of the velocity
