Success impacted (3)
I believe the answer is:
hit
This clue is a double definition.
'success' is the first definition.
(a hit is a commercial success)
'impacted' is the second definition.
(hit can mean to impact or crash into)
(Other definitions for hit that I've seen before include "Sock" , "recording in the charts" , "skier, perhaps" , "Badly affected" , "dose of illegal drug" .)
