From the question we are told that
The mass of the bob is
The angle is
The length of the string is
The tension on the string is mathematically represented as
substituting values
The motion of the bob is mathematically represented as
=>
Where is the angular speed
and is the phase change
At initial position S = 0
So
Generally can be mathematically represented as
Where T is the period of oscillation which i mathematically represented as
So
substituting values
Looking at the equation
We see that maximum velocity of the bob will be at S = 0
i. e
The maximum velocity is mathematically represented as
Where A is the amplitude which is mathematically represented as
So
Recall
substituting values
