After the cutscene, get in the car with Ryder and drive to B-Dup's apartment to trigger the next cutscene.
After the cutscene with B-Dup, drive over to the crack-dealer, kill him (spray paint him if you don't have anything else) and take the bat. Then drive over to the crack-den down the block, and prepare to see some crackheads and even a blowjob happening in the corner. Now beat everyone in the room up; if you have a gun, use that. Careful though, the man with the bat is also quite powerful, so kill him first.
Also, if you wish, search through the house and kill everyone in it. Most are so stoned they won't even defend themselves, and a single blow will take them out. However they don't seem to give any cash when killed.
Exit the building and drive Ryder home to complete the mission.
