I looked up static equilibrium in my textbook. We skipped that chapter. I'm actually really, really stupid when it comes to physics. Biology, chemistry, any other science, I'm good. Even calculus, I'm okay. Physics, not so much.
Okay, so I tried the free-body diagram. It's on a fixed pivot point, and supported on both ends, so the acceleration would be 0? I just thought it would be torque because the problem was posed in the notes for the chapter about torque.
Also, my professor emailed back...the answer is .91m...
Homework Statement
Word for word, from the problem:
"A person’s center of mass is easily found by having the person lie on a reaction board. A horizontal 2.5-m-long, 6.1 kg reaction board is supported only at the ends, with one end resting on a scale and the other on a pivot. A 60 kg woman...
