Is there a nice physical interpretation of this formula?
As a trivial example in our vector analysis class, we did the following computation.
Let $\overrightarrow{\omega} = (\omega_1, \omega_2, \omega_3)$ be the angular velocity and $\overrightarrow{r} =(x, …

Why do we only consider the monkey's translational energy and the pole's rotational energy? [closed]
The problem states:
A 50-kg monkey sits at the top of a 5-m high 200-kg pole. A worker saws through the bottom of the pole so that it falls on the side. With what speed does the monkey hit the floor …
