Answer:
686 N
Explanation:
OH BOY, NEWTONS LAWS OF MOTION!
look at this:
[tex]F = ma[/tex]
a fun fact is that acceleration 9.8 m/s^2 is actually GRAVITY.
so lets do this and rewrite the formula...
[tex]F = 70kg * 9.8 m/s^2[/tex]
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... [tex]6.9 * 10^{2}[/tex] N
NICE!
