- Homework Statement
- The center of mass of someone's thigh, shank, and foot are located at the following coordinates:

Thigh: (2.7, 3.2)

Shank: (2.1, 2.5)

Foot: (1.5, 1.9)

If the masses of them are respectively 9.6, 2.9, and 0.9 kg, where is the location of the entire leg?

ANSWER:

CM = (2.5, 3)

- Relevant Equations
- CMx = Xprox + L%*(Xdist - Xprox)

CMy = Yprox + L%*(Ydist - Yprox)

CMbody = E*(CMseg*Mseg)/Mtotal

If the masses of them are respectively 9.6, 2.9, and 0.9 kg, where is the location of the entire leg?

ANSWER:

CM = (2.5, 3)I'm having trouble figuring out the steps for this. I feel like I need to know the Length % in order to complete the formula but am lost as to how to get this. Thank you for any help you may be.
