In the dumbbell problem, we can solve without COM by using WPE and NLM. Like if I consider the theta with the horizontal from the second ball of dumbbell, then for the upper mass, there would be a T cos θ = N in x direction. Since N is zero, then T becomes zero. And for the lower mass, T also becomes zero. So there is no acceleration of the second mass in horizontal direction. Consider the velocity of lower mass to be v and upper to be u. Apply constraint relation. And then apply Work Energy theorem. We get two equations having v and u. From the Work Energy theorem equation, differentiate it to get acceleration. Since acceleration is zero, from there we get the value of theta. And then put it in the original Work Energy equation, you get your answer

16:28 Why do we consider the velocity of M ball if we are in COM frame should it not be 0 while conserving energy?
