Answer:
8 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)
m is the mass
f is the force
From the question we have
![a = (56)/(7) \\](https://img.qammunity.org/2021/formulas/physics/high-school/hq8g8hf5ppo4x70j3f24fyey30ext84fft.png)
We have the final answer as
8 m/s²
Hope this helps you
