Two scales support a massless plank from either end, separated by 3 m. A person, whose height is less than 3 m, lies down on the plank with their head on the leftmost scale. The leftmost scale reads F₁= 324 N, and the rightmost scale reads F₂= 100 N.

(a) Calculate the person's mass, in kg.

•  
(b) What is the location, in metres from the person's head, of their centre of mass?
