Given info : In SHM projection of uniform circular motion of a uniformly revolving particle on a circle, having Sense of rotation clock wise can be represented as x = 2 sin ( 2t + π/3) where x in cm and t in s.
To find : initial phase and period of revolution of particle are...
solution : equation of SHM is , x = 2 sin(2t + π/3)
initial phase, Φ₀ = value of (2t + π/3) at t = 0
= π/3 or 60°
as we know from standard equation of SHM , x = Asin(ωt + Φ₀)
on comparing we get, ω = 2 rad/s
but angular frequency, ω = 2π/T = 2
⇒T = π sec
Therefore period of revolution is π sec.

The initial phase is
π/3 = 180°/3 = 60°
time period of revolution = π seconds
