If the amplitude of displacement is small then small-angle approximation holds ie sin th th. Let us say after time t the final velocity of the object is v and the total displacement of the object is s. This leads to the equation for the velocity when the object reaches a given displacement from the starting point.
Displacement velocity x time.
