A particle moves in the x-y plane according to the equation
       $x = A \cos^2 \omega t$ and $y = A \sin^2 \omega t$
Then, the particle undergoes:

A particle executing simple harmonic motion of amplitude $5~\text{cm}$ has a maximum speed of $31.4~\text{cm/s}.$ The frequency of its oscillation will be:
1. $1~\text{Hz}$
2. $3~\text{Hz}$
3. $2~\text{Hz}$
4. $4~\text{Hz}$
