In Dead Rising 2 for the PS3, Xbox 360, and PC, there are a total of six explosive weapons scattered throughout the game you can collect. Use all six on a zombie to get the “Explosive Temper” achievement/trophy.
I’m uncertain if you need to just damage a zombie or kill them with each explosive, so it’s probably better to be safe than sorry and just kill them with it to be sure.
