600 * 6 / 9 = 400 newton
they have the same density That would be impossible. The only way to stop moving is to push down with you're feet each time you reach the ground

a pivot is the midle point
The effect would be that the nearer the pivot you have the load, the harder it would be to move the seasaw. The nearere the end, the easier it would be.
The force a lever can apply to a given point greatly depends on two distances:The distance from the pivot point to the object to be lifted and the distance from the pivot point to the point on the lever where force will be applied.To reduce the distance from the pivot-point to the point where Force is applied is to reduce the "force" of a lever.
Simple ..put equal weight at each end, equal distance from the pivot.
The see-saw needs to balance so the force on wither side of the pivot needs to be equal. The turning force is calculated by distance from pivot (in metres) by force. The side with the largest turning force will be lower than the other. If they are equal then the see saw will balance.
A seesaw would be a Class 1 lever. This is because the fulcrum(also known as a pivot) is in the middle of the load and effort.

if seesaw is balanced under its own weight with no added mass on it you cannot balance on one side. If it is unbalanced under its own weight u can add mass to balance on one side with mass depending on distance to pivot

A lever turns on a pivot == ==
fulcrum
Same thing as a seesaw. See the Related Link below for pictures.
