To determine the initial speed of a ball that is dropped from a certain height, let's consider the concept of how objects behave when they are simply dropped, not thrown.

1. Upon dropping an object from a height, it begins its motion from rest.
2. This means that initially, the object has no motion; it is not moving before it is dropped.

Given these observations, the initial speed can be considered as being zero because the ball starts from a stationary position.

Therefore, the correct answer is:
0 m/s

This is the initial speed of the ball when it is simply dropped from a height.
