Answer:
F = 40 [N]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the force applied on a body must be equal to the product of mass by acceleration.
∑F = m*a
where:
F = forces [N]
m = mass = 20 [kg]
a = acceleration = 2 [m/s²]
Now replacing:
[tex]F = 20*2\\\\F = 40 [N][/tex]
