$F = 50 N$

#### Explanation:

Lets suppose the force of the two kids is called ${F}_{1}$. Since they push in the same direction, the force is added.
${F}_{1} = 50 N + 50 N$
${F}_{1} = 100 N$
Lets suppose the force of the one kid pushing in the opposite direction is called ${F}_{2}$.
${F}_{2} = 50 N$
Forces in opposite directions have the difference as the resulting force. Lets call this rusulting force ${F}_{r}$
To calculate ${F}_{r}$ we subtract ${F}_{1}$ by ${F}_{2}$.
${F}_{r} = {F}_{1} - {F}_{2}$
${F}_{r} = 100 N - 50 N$
${F}_{r} = 50 N$
