One sunny day when Hunter was a pup, all his friends left the playground except him. He tried to balance a sizeable rock on the playground's 2.50 m seesaw plank with the fulcrum pivot point at the center. It didn't work. He moved the fulcrum to 0.50 m, placed the rock on the short end of the plank from the fulcrum, and balanced the seesaw. How would the rock's weight compare to the seesaw's weight?
