Answer:
The subordinate clause: when he laughed maliciously at the little girl
Function: adverb
Explanation:
A subordinate clause is a group of words with a subject and a verb that do not express a complete thought on its own, and an adverb clause is a type of subordinate clause that modifies a verb, an adjective or another verb, begins with a subordinating conjunction like when, since, unless, until, even though, and indicates place, manner, extent, time, cause or condition.
In the construction, while the clause “she kicked mike in the shins” is independent, the clause “when he laughed maliciously at the little girl” is subordinate because it does not express a complete idea on its own.
Furthermore, this subordinate clause is an adverb clause because it begins with the subordinating conjunction when, it modifies the verb kicked and it indicates time.
