You can't determine the acceleration of an object just by knowing its mass. Acceleration depends on both the 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. The equation is:

Force (F) = Mass (m) x Acceleration (a)

* To find acceleration: You need to know both the mass and the force. If you know the force, you can rearrange the equation to solve for acceleration:

Acceleration (a) = Force (F) / Mass (m)

Example:

* If a 60 kg object has a net force of 120 Newtons acting on it, its acceleration would be:

* a = 120 N / 60 kg = 2 m/s²
