At the bottom of it's swing. This is because it has accelerated to it's peak velocity due to gravity.
If you know the initial height and the length of the pendulum, then you have no use for the mass or the velocity. You already have the radius of a circle, and an arc for which you know the height of both ends. You can easily calculate the arc-length from these. And by the way . . . it'll be the same regardless of the mass or the max velocity. They don't matter.
Oscillation of a simple pendulum.
There are 3 Points at which the pendulum significantly changes direction. First it starts off pulled back before it is released it has a high potential energy because it is higher from the source of gravitation (generally the earth) but has no kinetic energy because it is not moving. Once released the pendulum loses potential energy and it swings downward and gains kinetic energy as it speed up. At the bottom of its swing it is going as fast as it will and has the highest kinetic energy and the lowest potential energy, then as it rises it loses the kinetic energy because it has to fight against gravity and loses kinetic energy and gains potential energy as it rises. And it repeats itself. One important thing to note is this is a great application of the law of conservation of energy because as it loses potential energy it gains the same energy in kinetic energy and vice versa (not counting the effects of wind resistance and friction however minor).
f=ma that in equilibrium postion the force are zero that why the in sample pendulum the force is zero that mean that acceleration is also zero that point velocity is maximum

When the pendulum is at its lowest point, it has the least potential energy. Therefore, logically, due to conservation of energy, its kinetic energy is at its maximum. Therefore its speed is also at its maximum, as well as its momentum (velocity x mass).

wind resistance cannot be ignored in considering a simple pendulum. The wind resistance will be proportional to a higher power of the velocity of the pendulum. A small arc of the pendulum will lessen this effect. You could demonstrate this effect for yourself. A piece of paper attached to the pendulum will add to the wind resistance, and you can measure the period both with and without the paper.
The velocity reaches a maximum, and the pendulum will begin to decelerate. Because the acceleration is the derivative of the velocity, and the derivative at the location of an extrema is zero, the acceleration goes to zero.

The whole point of a pendulum is that is swings back and forth. It does not travel at constant angular velocity: the angular velocity is zero at the two ends of its arc and it reaches a maximum when the pendulum is vertical. Consequently there cannot be a sensible answer to the question as asked.The average angular velocity, which is an entirely different measure, is 45 degrees per second.
When a pendulum reaches its maximum elongation the velocity is zero and the acceleration is maximum
f=ma that in equilibrium postion the force are zero that why the in sample pendulum the force is zero that mean that acceleration is also zero that point velocity is maximum
A moving pendulum stores a certain quantity of kinetic energy, whose expression is T = 0.5 L M w^2 where L is the pendulum length M the pendulum mass w the pendulum angular velocity (radiant per second) It is possible to device different methods to transform this energy in electrical energy, for example by charging the pendulum mass and moving it into a solenoid, much like an electrical generator. The result is that the pendulum is slowed more and more up to stop and, while the pendulum speed decreases, electrical energy is created. The total electrical energy E that can be created is E=T-R where R>0 are the unavoidable losses of the system.
