Given that,
Velocity of a simple harmonic oscillation is
......(I)
We know that,
Formula of velocity of a simple harmonic oscillation
....(II)
On comparing equation (I) and (II)
A is amplitude.
We need to calculate the maximum velocity
Using formula of acceleration
Put the value into the formula
Hence, The maximum velocity is 12 m/s.
(2) is correct option.
