1. The problem statement, all variables and given/known data The 0.6 lbf slider moves freely along the fixed curved rod from A to B in the vertical plane under the action of the constant 1.3 lb tension in the cord. If the slider is released from rest at A, calculate its velocity v as it reaches B. I have attached an image of the question 2. Relevant equations 3. The attempt at a solution As far as I can tell this is an energy problem, hence: T1 + V1 + U1-2 = T2 + V2 T1 and V1 are zero as there is no initial energy, spring forces or gravitational forces at A. Hence, I get: (13/12)sin(67.38) = 1/2*(.6/32.3)v2b - 0.6*(10/32.3) v = 11.28 Not quite the answer I'm looking for and I'm a little unsure where I'm making my mistake. Any help would be appreciated.
