To determine the location of his center of mass, a physics student lies on a lightweight plank supported by two scales L = 2.40 m apart If the left scale reads 278 N, and the right scale reads 116 N, calculate the student's mass.
Calculate the distance from the student's head to his center of mass.

Hmmmm. sum moments about the Left end.
116*2.4-(116+278)x=0
find x, the distance of the cg from the left end.

The student's weight is equal to the summation of the two reactions or 394N which is equal to 40.2 kg force.
