A particle moves uniformly around the circumference of a circle whose radius is 8.0 cm with a period of $\pi$/20 s.The angular velocity $\omega$ of the particle is A)2.5 rad/s B)3.2 $\times$ 10² rad/s C)40 rad/s D)7.9 rad/s E)0.96 rad/s

Question

Quizplus · Accepted Answer

The angular velocity ω is given by ω = 2π/T, where T is the period. Given T = 0.20 s, ω = 2π/0.20 = 10π ≈ 31.42 rad/s, which is closest to 40 rad/s.
