Question

A Polishing wheel moves At 150 Revolutions per minute. Calculate the Angular Velocity of the Polishing wheel

Answer 1

Answer:

ω = 5π rad/s

Step-by-step explanation:

Each revolution is 2π rad. The angle (θf – θi) = (150) x (2π rad). The time, t, is 1 min, or t = 60 s. Use the formula for angular velocity.

ω = (θf – θi) / t

ω = (150 x 2π ) rad / 60 s

Solve: ω = 300π rad / 60 s = 5π rad/s
