Hi again
,
here's another one of my find picture questions. In the following picture I had a guy on one hand. Now, it says the ground reaction force is 1000 N and I have to resolve this force into it's vertical and horizontal components.
One hand position
My questions are:
1)The ground reaction force is just straight up correct? It is also equivalent to the one going straight down. F=mg. So that would be the vertical component...
2)This is the confusing part? How could I resolve into horz and vert if that's already the vertical? On the picture I drew what I think is correct but...
3)I can't find a way to solve for these components with only one piece of info? Unless I don't have to...it asks to resolve into components, does that mean I have to solve as well?
4)Oh, and last question about center of mass...is it true that if I drew straight lines from each say fot and hands, that the convergent point is usu where the center of mass lies? :yuck: :yuck:
Any help appreciated!
