Need Help ASAP! Magnitude and Forces problem

[sfs007]

Based on a free body diagram of a runner running around a turn on a track:

 

1. An estimate of the lean you would have while running at your maximum speed on a university track and

2. estimates of the relative distances between your mass center and the various forces depicted in the free body diagram, and

3. an estimate of the magnitudes of the forces depicted in the free body diagrams,

 

You should:

Calculate the magnitudes and directions of the moments produced about the mass center by each of the forces shown in the free body diagram. The moment magnitudes should be given with appropriate units or dimensions.

 

Weight is 150lbs or 68kg

Height is 5'8

What have you got so far?

I have no idea where to start!

I am in grad school for health promotion but in a biomechanics class and I have no idea when it comes to physics!! And this is the only problem I have to do in this class and I just wanna get it over with! haha I have a free body diagram on a runner leaning on a turn and thats it!
