3. A 75kg man sits at one end of a uniform seesaw pivoted at its center, and his 24kg son sits at the
other end. Where would his 55kg wife have to sit to balance the seesaw?

And by the studying of the Newton's law we can find the equation useful to find the distance of the mother sitting on the seesaw with respect to the center ot the pivot point.

A logical intuition will give us the idea that the mother will be on the side of her son to make the balance.

The maximum momentum with respect to the pivot point (0) will be:

[tex]M=75 *\frac{L}{2}[/tex]

Where L/2 is the half of the distance of the seesaw

Therefore the other loads ( mom + son) must be create a momentum equal to the maximum momentum.
