Not quite sure what to do about this one:(adsbygoogle = window.adsbygoogle || []).push({});

-----A person whose weight is W = 601N is doing push-ups. Assume L1 = 0.859m and L2 = 0.353m. Calculate the normal force exerted by the floor on each hand, assuming that the person holds this position. ------

I can't get the picture on here, but basically it shows a person in the postion of a push up. L1 is from his feet to the center of gravity (in his stomach in the picture). L2 is from the center of gravity to his hands. I know the equation for center of gravity is Xcg = W1X1 + W2X2 +... / W1 + W2 +...

I'm not really sure what to do with this. I thought maybe I would calculate for the center of gravity and just multiply by gravity to get the normal force...? Any guidance would be appreciated. Thanks :)
