F=50NF=50N

Explanation:

Lets suppose the force of the two kids is called F_1F1. Since they push in the same direction, the force is added.
F_1=50N+50NF1=50N+50N
F_1=100NF1=100N
Lets suppose the force of the one kid pushing in the opposite direction is called F_2F2.
F_2=50NF2=50N
Forces in opposite directions have the difference as the resulting force. Lets call this rusulting force F_rFr
To calculate F_rFr we subtract F_1F1 by F_2F2.
F_r=F_1-F_2Fr=F1F2
F_r=100N-50NFr=100N50N
F_r=50NFr=50N
