The speed is zero.
At position D, the speed of the pendulum ball is at its lowest value.
To determine the speed of the pendulum ball at position D, first, we need to understand the motion of a simple pendulum. A simple pendulum consists of a mass (ball) tied to a string or rod that hangs from a fixed point and swings back and forth due to the force of gravity.
At position D, the pendulum ball is at its maximum displacement from the equilibrium position (midpoint). At this point, the speed of the pendulum ball is at its highest value. This is because the gravitational potential energy is converted into kinetic energy as the ball falls towards the equilibrium position.
Therefore, the correct response is "The speed is at its highest value."
