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.
