Answer:
2 m/s^2
Explanation:
Newton's second law gives us the relationship between force, mass and acceleration:
[tex]F=ma[/tex]
where
F is the force applied
m is the mass
a is the acceleration
In this problem, we have:
m = 70 kg is the mass
F = 140 N is the force
Solving the equation for a, we find the acceleration:
[tex]a=\frac{F}{m}=\frac{140 N}{70 kg}=2 m/s^2[/tex]
