Dimorphos’ physical appearance seems to suggest a loose structure.
I haven’t read much about its makeup, maybe I’m wrong, but I wonder just how much of that impact was absorbed by that material.

100% of the projectile's (impactor's) momentum was absorbed by Dimorphos. (Where else could it have gone?!) Some of that momentum was converted into heat.
