The force is an additive quantity allows to find the result for the total force exerted by the two people is:
[tex]F_{total}[/tex] = 54 N
Newton's second law gives a relationship between the net force, the mass and the acceleration of the body, when the acceleration is zero, this expression is called the equilibrium condition.
∑ F = 0
Where F is the force that is a vector quantity and therefore additive.
They indicate that the two people pull with a force of 23 N and 31 N in the same direction.
[tex]F_{total} = F_1 +F_2[/tex]
Let's calculate.
[tex]F_{total}[/tex] = 23 +31
[tex]F_{total}[/tex] = 54 N
In conclusion, using that force is an additive quantity, we can find the total force exerted by the two people is:
[tex]F_{total}[/tex] = 54 N
