Answer:
The answer is 2 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)
where
f is the force
m is the mass
We have
![a = (40)/(20) = (4)/(2) \\](https://img.qammunity.org/2021/formulas/physics/college/lm5eqepfcbgx0h73a8fl0ztap7awez3yhg.png)
We have the final answer as
2 m/s²
Hope this helps you
