radius of gyration:
r = root (I/m)
I = moment of inertia
m = mass
parallel axis theorem given above
The Attempt at a Solution
Okay, so I think the moment about CM is just m*0.24^2, but after that, I'm less sure.
Is the moment about the hip just m*0.42^2 + m*0.24^2?
If so, it's taking the acceleration and the distance to the toe into account that I'm having difficulty with. Is it just F = ma? If so, is the m taken from the moment of inertia at the hip, or the toe? I figure the distance to the toe must be significant, but I don't know how to account for it.
