A 1.80 m long thing rod is balanced vertically on its tip on the floor. It starts to fall and its lower end does not slip. What is its angular speed just before it hits the floor?
The Attempt at a Solution
When I first started this problem I had a better grasp, but as I started thinking about it I'm pretty sure I got further away. I started finding accelerations and velocities instead of getting back to the angular speed part of the problem. Now I'm trying to figure out how to actually do the problem. What is the first step?
