1. The problem statement, all variables and given/known data Mass of both end, distance from the pin point, height of the plug and its mass, angular velocity are given. Need to fine angular velocity w of the arm immediately after plug has wedged itself in the block. 2. Relevant equations (Ho)o = (Ho)horizontal 3. The attempt at a solution 1) 2(v1)(0.5) = (4+2)(0.5w)(0.5) + 6(0.3w)0.3 2) v^2 = vo^2 - 2g(y-yo) -> calculate v and substitute in v1 I find w to be a number smaller than 2 rad/s which is given and i know it's CW. I just want to double check my work. thanks.
