1440 revolution per minute is equal to 150.8 radians per second :

$$1440 \text{rpm} = 150.79644737231007 \text{rad/s}$$

To convert from revolutions per minute (rpm) to radians per second (rad/s), you can use the following conversion factors:

• 1 revolution = $2\pi$ radians
• 1 minute = 60 seconds

Given the conversion:

$$1 \, \text{rpm} = \frac{2\pi}{60} \, \text{rad/s}$$

To convert 1440 rpm to rad/s:

$$1440 \times \frac{2\pi}{60} \, \text{rad/s} = 1440 \times \frac{\pi}{30} \, \text{rad/s} \approx 150.8 \, \text{rad/s}$$

Therefore, 1440 rpm is approximately 150.8 rad/s.
