Answer:
4 m/s²
Step-by-step explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
![a = (f)/(m) \\](https://img.qammunity.org/2021/formulas/mathematics/college/f1nfur3dv1q3xis9z9jehstfpeb6xsi32a.png)
f is the force
m is the mass
From the question we have
![a = (12)/(3) \\](https://img.qammunity.org/2021/formulas/physics/college/x3lcgwjyumnzi2y2rjpaxdkn1a2xbyf8de.png)
We have the final answer as
4 m/s²
Hope this helps you
