Question

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, as indicated in the figure(Figure 1) . If the left scale reads 300N , and the right scale reads 112N.

A) FInd the students mass.

B) Find the distance from the student's head to her center of mass.

Thanks!!

Explanation / Answer

No link to the figure, so we'll muddle through without it.

The student's weight is the sum of the values on the scales: 300 + 112 = 412.

Compute the location of the center of mass from

( 320 ) ( d ) = ( 2.50 - d ) ( 112 )

The answer, d, is the distance from the scale that reads 320 to the center of mass.
