Using momentum balance:
The 588 N mother is on the other side of the seesaw, 2.20m away from the pivot
F1 = 588 N
x1 = 2.20 m
Two of her children sat on the other side:
F2 = 256 N
x2 = 2.00 m
F3 = 412 N
x3 = unknown
F1x1 = F2x2 + F3x3
Solve for x3:
588 * 2.2 = 256 * 2 + 412 * x3
x3 = 1.90 meters away from pivot
