Explanation:
From the question we are told that
The spring constant is
The maximum extension of the spring is
The number of oscillation is
The time taken is
Generally the the angular speed of this oscillations is mathematically represented as
where T is the period which is mathematically represented as
substituting values
Thus
this angular speed can also be represented mathematically as
=>
substituting values
In SHM (simple harmonic motion )the equation for velocity is mathematically represented as
The velocity is maximum when
=>
=>
=>
