Question

A particle is describing the circular path of radius 20m in every 2second .The average angular speed of the particle during 4 second is?

Answer 1

Answer:

ω = 1.57 rad / s

Explanation:

r = 20 m     &     t = 2 s

v = r ω

ω = v / r = 2 π r / r t

ω = 2 x 3.14 / 4

ω = 1.57 rad / s

Answer 2

Answer:your answer is here:v/r =W therefore.we have to find its linear velocity after 4 sec but vel is constant then after 4 sec vel remain same speed=d/t .total distance cover = 4pie×r velocity= 20pie therefore angular speed = 20pie/20= pie
