1. The problem statement, all variables and given/known data A mass is dropped from height (h) onto one end of a stick of mass (m) and of length (l) pivoted around the opposite end. The moment of inertia of the stick is 1/3ML^2. Upon collision the mass adheres to the stick. a. Find speed of mass just before impact b. Find angular speed of the system immediately after impact c. Find linear speed of the mass (m) at its lowest point (when stick is vertical) d. Determine the mechanical energy lost as a result of the collision. 2. Relevant equations Conservation of angular momentum angular kinematics equations 3. The attempt at a solution For the first part I think I found easily with vf^2=Vo^2+2ah which will get you vf=(2ah)^1/2 The last three parts I am very confused about. I have that Io wo=If wf The last part I would think I would use the kinetic energy at the start and at the bottom.
