Answer:
10 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/2022/formulas/physics/high-school/s55mabkzmc58r8y1m5yehv8vnu19espr3s.png)
m is the mass
f is the force
From the question we have
![a = (70)/(7) = 10 \\](https://img.qammunity.org/2022/formulas/physics/high-school/bihjxtn7xuuh8a34tfdtsdpohvq4d4yfan.png)
We have the final answer as
10 m/s²
Hope this helps you
