1. The problem statement, all variables and given/known data A ball of mass m is attached to a rigid vertical rod by means of two massless strings each a length L. Both strings are attached on the rod a vertical distance D apart. The rod, strings, and ball are rotated at some speed and both strings are taught. If the tension in the upper string is given as FT, find the speed of the ball and the tension in the lower string. 2. Relevant equations F=ma a=v^2/r 3. The attempt at a solution look at my pictures in the attachments... kinda hard to do physics problems online in my opnion. The problem is I feel like the teacher didnt make the question clear enough. can we assume that both strings are at the same angle? can we assume that the y-acceleration is 0? also, I didnt even use the value D at all....so i feel like i MUST be going wrong somewhere. the first attachment is the entire problem, but if you cant read it, then i've attached 3 more close ups. THANKS!
