# How Fast Does the Blade of an Electric Saw Rotate?

## What is the angular speed of the blade of an electric saw?

The blade of an electric saw rotates at 2800 rev/min. What is the angular speed in rad/s?

## Angular Speed of the Blade of an Electric Saw

The blade of an electric saw rotates at 2800 rev/min. To convert this angular speed to rad/s, we need to use the formula:

Angular speed in rad/s can be calculated by multiplying the angular speed in rev/min by 2π/60, which is the conversion factor from revolutions to radians and minutes to seconds. Let's do the calculation:

Angular speed = 2800 rev/min

Angular speed = 2800 * 2π/60 rad/s

Angular speed ≈ 293.2 rad/s

Therefore, the angular speed of the blade of an electric saw is approximately 293.2 rad/s.
