A person is 68 in (173 cm) tall (H) and has a mass of 160 lbs (73 kg) (W) and you are going to estimate this person's center of gravity using the scale technique that was performed in Lab 2. The tare weight of the board (B) is 13.5 lbs (6.1 kg), and the partial weight of the person and the board (S) is 93.5 lbs (42.5 kg). Assume that the length (L) of the board is 200 cm. What is the distance (d) from the bottom of this person's feet to their center of gravity?

Options

A- 87cm

B- 116cm

C-100cm

D- 78cm
