Known iviass Unknown Mass 3 m- Fulcrum An experiment is performed by placing a known mass with its center of mass a distance of 3 meters from a fulcrum, as shown above. An unknown mass is used to balance the system, with its distance from the fulcrum not completely measurable. Every ti known mass is changed, the unknown mass is moved until equilibrium is reached. The data that were gathered for this experiment are below. Known mass (kg) Unknown mass location (m) 85

An experiment is performed by placing a known mass with its center of mass a distance of 3 meters from a fulcrum, as shown above. An unknown mass is used to balance the system, with its distance from the fulcrum not completely measurable. Every time the
known mass is changed, the unknown mass is moved until equilibrium is reached. The data that were gathered for this experiment are below.

Pool
Students are doing an experiment near an empty pool. A student of mass 40 kg is standing on one end of a board as the board hangs over the pool as shown. The board is of uniform density, has a length L, and is positioned such that the pivot point is L/3 from the
end of the board. The board is just about to tip over into the pool. How far from the pivot point must a 60 kg student stand so that the board is just about to tip over?
