THIS IS NORMAL.
dont worry, a lot of cats are scared when they go to some place totally new. you shouldnt force her out sometimes they can bite and scratch. while shes hiding you can talk to her quietly or give her some toys to play with. it may take up to a few days for a cat to get used to new places let her explore the house and try to keep it quiet (sometimes loud noises can make new cats really freaked out.)

GOOD LUCK!!!!!!!!!!!!!
