The SI unit for angular velocity is radians per second. However, it is frequently presented with a different unit, namely, radians per second.

Here are two non-SI but very common units for angular velocity: $$ \text{rps} = \text{rotations per second} = \frac{\text{rotations}}{\text{second}} $$ and $$ \text{rpm} = \text{rotations per minute} = \frac{\text{rotations}}{\text{minute}} $$

You can convert these to quantities using the following conversion factors

Convert each of the following quantities to radians per second, the SI unit, using the conversion factor method correctly.

- Convert 50 rps to radians per second.
- Convert 120 rps to radians per second.
- Convert 2 rpm to radians per second.
- Convert 30 rpm to radians per second.
