#### Solution

Given:-

`a=1cm,t=pi/3s,omega=(2pi)/T=(2pi)/(2pi)=1`

To find: Displacement (x)

Formula: x = A cos ωt

Calculation: From formula,

`"x"=1cos(1xxpi/3)=cos(pi/3)`

`therefore"x"=0.5cm`

**The displacement of the particle after π/3 seconds is 0.5 cm.**

Concept: Periodic and Oscillatory Motions
