The term "implosion" typically refers to a process where something collapses or inwardly disintegrates, often due to external pressure or forces. It does not have a specific speed associated with it, as it can vary depending on the circumstances and the object or system undergoing implosion.
The speed of an implosion can depend on various factors such as the strength of the external pressure or force, the structural integrity of the object or system, and the materials involved. It is difficult to provide a precise answer without specific details about the situation in question.
For example, in the case of a controlled implosion of a building, the process is carefully planned and executed to ensure a controlled collapse. The speed of the collapse can vary depending on the demolition techniques used and the size and structure of the building.
In summary, the speed of an implosion can vary widely depending on the specific scenario, and it is not possible to provide a general or specific speed without more information about the circumstances.
