Time is a major component of g force tolerance. Healthily people can take 15g’s for short periods without issue, but extend that to a minute and it can prove deadly.
In ideal conditions linear acceleration to Mach 2 at 5, 10, even 20g is fine. But, if you want to go much faster the limits are reduced significantly. The Soyuz for example can hit 8.5g’s for about 60 seconds in some situations which adds up to ~Mach 14.6 and is a rather extreme situation.
