1. The problem statement, all variables and given/known data A 2.00-kg ball is attached to the bottom end of a length of 10-lb (44.5-N) fishing line. The top end of the fishing line is held stationary. The ball is released from rest while the line is taut and horizontal ([tex]\theta[/tex]) = 90.0 degrees). At what angle [tex]\theta[/tex] (measured from the vertical) will the fishing line break? 2. Relevant equations Conservation of Energy: Ki + Ui = Kf + Uf 3. The attempt at a solution I'm pretty sure that I have to start with the conservation of energy equation, however, I am not quite sure that I have enough numbers to put in to solve for anything. Also, I have no idea what circumstances would cause the fishing line to break. I'm just clueless as to where to begin here.
