You can't determine the acceleration of an object just knowing its mass. Acceleration depends on both mass and the net force acting on the object.

Here's why:

* Newton's Second Law of Motion: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically:

* a = F / m

Where:

* a = acceleration

* F = net force

* m = mass

To find the acceleration, you need to know the net force acting on the object.

Example:

* If a 11 kg object has a net force of 22 Newtons acting on it, its acceleration would be:

* a = 22 N / 11 kg = 2 m/s²
