Answer:
686 N
Step-by-step explanation:
OH BOY, NEWTONS LAWS OF MOTION!
look at this:
![F = ma](https://img.qammunity.org/2022/formulas/physics/college/tapnqkh0zd9dttqw8rz3d1q51zr1jh4hej.png)
a fun fact is that acceleration 9.8 m/s^2 is actually GRAVITY.
so lets do this and rewrite the formula...
![F = 70kg * 9.8 m/s^2](https://img.qammunity.org/2022/formulas/physics/high-school/zwria0dzdx9g2en3u1ewmo4f8nexq63o8r.png)
lets multiply 70 and 9.8
we get 686 N.
if you want to be technical about it...... the answer should only have two sig figs. so it would be...
N
NICE!
