- Relevant Equations:
- Moment of inertia of end rod = 1/3ml^2
I was wondering why in the video the moment of inertia for the clay ball (upon collision) was simply 1ml^2. That is the constant for a hollow cylinder. The problem specifies that the object is a ball, so the cylinder classification makes no sense, and also I'm pretty sure clay is rather dense of a material.
Shouldn't it instead be 2/5ml^2? That is the constant for a solid sphere through its center.
