An actor stands 2m in front of a spotlight that is dropping above the ground. The actor is 1.6m tall. The length of his shadow on the ground is increasing at a constant rate of 0.8 m/s. Find the speed at which the spotlight is dropping when the spotlight is 4 m above the ground, assuming the actor stays in the same position.
