    What is the Equivalent Resistance between Points A and B in this Circuit?

    Here it is: 1/Req1 = 1/55 + 1/R = 1/55(R/R) + 1/R(55/55) = R/55R + 55/55R = (55+R)/55R Req1= 55R/(55+R) 12 + 55R/(55+R) = 27 12 + 55R = 27(55+R) 55R = (27-12)(55+R) 55R = (15R) + (15 x 55) 40R = 825 R = 20.625

    Woman in Elevator Problem (Free Fall), Forces she experiences?

    Hello, first post. I hope that someone can help me with this. I will roughly summarize the problem, and what I've done thus far. Homework Statement A lady was in an elevator that free-fell 6 feet and abruptly came to a halt. We had to determine a reasonable best case and a reasonable worst...
