Answer to Question #329003 in Physics for Ggg

Question

When the blender is empty and running at high speed, how much time is required for a blade to turn by 90 degrees

Answer 1

This depends on the angular speed (angle per second) of the blades. Let's denote it as $\omega$. Then the time required to turn by $\phi=90\degree$ is given as follows:

$$t = \dfrac{\phi}{\omega }$$
