1. The problem statement, all variables and given/known data In Fig. 11-59, a small 0.340 kg block slides down a frictionless surface through height h = 0.336 m and then sticks to a uniform vertical rod of mass M = 0.424 kg and length d = 1.69 m. The rod pivots about point O through angle θ before momentarily stopping. Find θ 2. Relevant equations image at http://www.lowellphysics.org/beta/T...m/Problems/c11x11_14.xform_files/nw0627-n.gif 3. The attempt at a solution I feel like if manipulated a million different things but just end up with something unsolvable. I tried using conservation of angular momentum to find the initial angular momentum of the system. and then i tried finding the net torque and relating this to the inertia of the system. At the end i have to many unknown quantites to solve for theta. Trying to get rid of angular acceleration, I end up with 1.376^2=theta(13.3)sin(theta)....and i don't think there is a way to solve that...so there must be another way to do this problem... i think if i knew the angular acceleration of the system, i could solve the problem, but i don't. haha...any help would be appreciated.
