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]
