As someone said earlier it all depends on the rider. Fighter pilots often experience up to 10G's and dont even pass out, while others pass out at 4. I would say 5 is definately within limits for about 2 seconds, so you should be alright there.
yes, but fighter pilots also have a lot of training, and build "immunity" against high g forces, but they can still pass out if they experience the g's for far to long.
