1. The problem statement, all variables and given/known data A 200 gram body pierced string can slide through a 1.8 m string, tied at points A and B to a vertical rod around which rotates so that the segment BC is flat. Calculate the speed of the body. I don't know where I have to put the body to solve the problem. Here is the schematic: http://imageshack.us/photo/my-images...ciofsicat.jpg/ I also give the length of the vertical rod, which is 1.2 m. I guess there should draw any trigonometric relationship, find an angle to work with the components. But again, do not know where I put the body to raise the exercise. Thank you!
