Question

A particle takes 7 seconds to complete one revolution. what will be its angular speed?

Answer 1

Answer:

Explanation:

Hey,

=>  Here, A particle takes 7 seconds to complete one revolution.

t = 7 s

=> We can use below Formula to find angular speed:

ω =θ/t

where,

ω = angular speed

θ =  angle of rotation

t = the time to complete the rotation.

=> but, for  1 full circle(revolution) θ = 2π rad

∴ omega, ω =2π/t

=> ω = 2×3.14/7

ω = 0.897 rad/s

Thus, the  angular speed of a particle is 0.897 rad/s.
