The angular speed of the turntable is approximately 10.47 rad/s or 599.8 degree/s.

Given: 100 rev/min

Conversions:

1 min = 60 s

1 revolution = 2π radians

1 revolution = 360 degrees

Angular speed in rad/s:

ω = 100 rev/min * 2π radians/rev * 1 min/60 s

ω ≈ 10.47 rad/s

Angular speed in degree/s:

ω = 100 rev/min * 360 degrees/rev * 1 min/60 s

ω ≈ 599.8 degree/s

Question:-

A turntable rotates at 100 rev/min. Calculate the angular speed in rad/s and in degree/s.
