One rpm is equal to _ rad/sec
Correct answer: D. 0.105
- A. 2
- B. 1.5
- C. 2.5
- D. 0.105
Explanation
One revolution is 360 degrees or 2π rad. Since it's 'Revolution per minute', it would be 2π rad/1 min or 2(3.142)/ 60 seconds; 0.1047 rad/sec or 0.105 rad/sec.

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.
