Question 1039996: four boys are playing tug of war. The two boys on one side are pulling with forces of 80 N and 70 N. If the forces of the two boys on the other side are such that one is double the other, what is the resultant force?

You can put this solution on YOUR website! four boys are playing tug of war. The two boys on one side are
pulling with forces of 80 N and 70 N. If the forces of the two
boys on the other side are such that one is double the other,
what is the resultant force?
That would depend on whether the rope is moving.
If we assume that the rope is not moving, then the resultant
force on the rope is 0.
Is this a trick question?
Maybe you're asking for the tension in the rope if the rope is
not moving.
In that case, the tension is the sum of the forces on each side,
so it's 80N+70N=150N on each side, so the tension in the rope is
twice that or 300N.
Maybe you want to know what forces the boys on the other side are
pulling at. If so, then:
x + 2x = 150N
3x = 150N
x = 50N
So one boy is pulling at 50N and the other twice that at 100N.
It is not clear what you are asking. Maybe it really is a trick
question and the resulting force is 0, since the forces in
opposite directions cancel each other out.
