Question
An object is executing uniform circular motion with an angular speed of `pi/12` radians per second. At t = 0 the object starts at an angle θ = 0 What is the angular displacement of the particle after 4 s?
Solution
ω = `π/12` rad/s
ω = `θ/t`
θ = w x t = `π/12` x 4
θ = `π/3` radian
θ = `"180°"/3`
= 60°
