Final answer:
If an object is accelerating at a rate of 3m/s/s and its mass is decreased by a factor of 2, the new acceleration will be 3m/s/s.
Step-by-step explanation:
When the mass of an object is decreased by a factor of 2, its acceleration remains the same. In this case, the object is accelerating at a rate of 3 m/s².
So, the new acceleration will also be 3 m/s².
