Question
A 750-N physics student carries a 4.0 meter board, uniform in shape, and 190 newtons in weight to our swimming pool. The student then places the board on the deck and next to the pool in such a way so 1.5 meters of the board extends out over the edge of the pool. How far, in meters, may the student walk out onto the board, with tipping?

the cb of the board, from the end, is 2 m, or .5 m inland.
Sum moments about the edge of the pool.
.5*190-d*750=0 for stability
solve for d, the distance she can walk out from the edge.
Think out the equation I wrote.
