6. If an object has an acceleration of –3 m/s?, describe its motion.

Its motion is accelerating backward or changing velocity in a backward motion.

Explanation:

We know acceleration is a vector quantity, therefore, containing both magnitude and direction. The negative sign represent direction so here, it's representing a backward motion. The magnitude here is 3, meaning that is is moving at a changing velocity of 3 m/s, meaning each second, the velocity increases 3 m/s going backward.

mass and volume are the answers you are looking for
