1. The problem statement, all variables and given/known data Tarzan mass M swings from a vine from rest at height H. At the bottom of the arc he picks up Jane of mass m in a perfectly inelastic collision. They reach a vertical height h. How far vertically above h is H? 2. Relevant equations Pi = Pf R = [tex]\Sigma[/tex]mr/[tex]\Sigma[/tex]m 3. The attempt at a solution Using conservation of momentum: Mv1 = (M + m)v2 Center of mass: (MH + (m+M)h)/(m + M) I feel as though these must somehow be related to find the distance, but after looking for quite some time now, no obvious correlations are coming. I would appreciate any help in getting me in the right direction. Thanks!
