Ellie Rose can hold onto a knife imbedded in the side of the Toppat Orbital station while it's taking off, being able to completely withstand the thrust it's producing.
To actually calc this I'm using these formulas:
Resultant Force = Thrust (What we want) - Weight
Acceleration = Resultant Force / Mass
I've already calculated the mass of the orbital station (11,503,598,087.8 Kilograms, multiplied by 9.80665 to get 112,811,760,188 Newtons), and for acceleration I'm going to assume the station was accelerating at a similar rate as normal space ships, which take 8 seconds to reach 161 Kilometers/Hour (44.722222 Meters/Second, getting acceleration to be 5.59027775 Meters/Second^2) and 1 minute to reach 1,609 Kilometers/Hour (446.94444 Meters/Second, getting acceleration to be 7.449074 Meters/Second^2)
7.449074 = R/112811760188
Resultant Force = 840,343,149,710.666016 Newtons
840,343,149,710.666016 = Thrust - 112,811,760,188
Thrust = 953,154,909,898.666016 Newtons, divided by 9.80665 to get 97,194,751,510.3 Kilograms, Class G
