Problem
A massless 4.0 m board rests on a support at its center. An 80 N box is placed 1.0 m to the left of the support. A worker can stand anywhere up to 1.5 m to the right of the support and can push downward on the board with a maximum force of 60 N. Determine whether the worker alone can restore the board to rotational equilibrium without exceeding the 60 N limit, and justify your answer with a calculation of the required force.
