    How Do You Calculate the Center of Mass for a Three-Mass System?

    I'm having a difficult time with this question, and I'm sure it's easy. The question is, find the center of mass of the three-mass system. Specify relative to the left-hand 1.00kg mass. Mass1 = 1kg Distance = 0m? Mass2 = 1.5kg Distance = .50m Mass3 = 1.1kg Distance = .75m I'm...

    Quick and Easy Set Questions: Understanding the Concept of Elements in Math

    Need some help on some of these problems. Thanks in advanced. Ø E = is an element of... 1. Ø E {{Ø}1,2} False? I'm a little confused. Is Ø on the left side a set? So, can it be equivalently written as {Ø}? If so, then it can't be an element of something, since it's actually a set, or in...

    [Calc2] Question about convergence of series.

    Yes, it is this: I don't know how to do that. https://www.physicsforums.com/latex_images/35/356726-0.png Why would I use 5/7^n? I'm confused. The limit as n-> infinity of (4n+3) / (7n-1) is 4/7, correct?

    [Calc2] Question about convergence of series.

    I have this series E(n=3) = (4n+3) / (7n-1)... going to infinity. I'm not quite sure how I would go about solving this. Do I use the comparison test? Any help would be greatly appreciated. Thank you.
