1. The problem statement, all variables and given/known data Determine force vs angle, that acts on the vertical wall from the falling dumbbell. Dumbbell falls without initial velocity. The mass of each bead of dumbbell is m. 2. Relevant equations The problem need to be solved using only Newton's equations by writing them for each of the material points. 3. The attempt at a solution I do not know how I find the acceleration of the points.
