To determine the location of her center of mass, a physics student lies on a lightweight plank supported by two scales 2.50 m apart. If the left scale reads 290 N, and the right scale reads 122 N, find: the student's mass the distance from the head to the student's center of mass

Explanation / Answer

a) [290+122]/2*9.8=21.02kg

b) 290*x=122(2.5-x)

290x=305-122x

x=305/412= .74m
