Re: 190,000lb of thrust?
" the mass of the Falcon 9 as 549,054kg"
You might need to add in the mass of the payload as well. But you're probably correct about the figure being for all 9 engines, not each.
A typical rocket should have "just enough power" to exceed 1G of acceleration at the moment it launches. In fact, Saturn V had to burn fuel for a couple of seconds before it actually left the launch platform (it was still just a 'tad' too heavy at T minus zero). Saturn V started its engines at T minus 3 [I think that's right], throttled up with the fuel lines connected, and at T minus 0, it ejected the fuel lines and the tower moved out of the way with the engines running at full capacity for a couple of seconds before actual lift-off. Something like that.
And the Space Shuttle had to do a 'throttle back' while the SRBs were attached, to limit stress during certain parts of the launch. I'd expect that the Falcon 9 does something like this as well, so it won't be running "balls to the walls" during the entire trip.
