In the previous question, we learned that the perfect speed |Vp| required so that the 4 bodies rotate in a circle that inscribes the square, is determined by the equation: oo
W = § F dr
R
I compute how much work is needed to move the 4 bodies to oo, and then say that in absence of this external force, then to reach oo, a body needs enough KE to compensate for the work performed against gravity. So, set KE = W (and I believe that this is another way of expressing the KE/PE formulations given in some posts).Join the community of 500,000 technology professionals and ask your questions.
