rev/min is equal to:
Correct answer: D. π/30 rad s -1
- A. π/6 rad s -1
- B. π/16 rad s -1
- C. π/20 rad s -1
- D. π/30 rad s -1
Explanation
The answer can be calculated as:1rev=2π1min=60srev/min=2π /60s =π /30.

About Angular Velocity
Angular velocity describes how quickly angular displacement changes with time, with ω = Δθ/Δt and units of radians per second. Questions relate angular and linear motion through v = rω, use the direction given by the right hand rule, and distinguish angular velocity from angular acceleration and ordinary frequency.
