Need help on thia is so confusing to me

So Lift = CL1/2pV^2S

At the point of lift off, the lift force has to balance the weight of the aircraft.

It says it's loaded to 92% of it's MTOW (347,452kg if I'm reading it correctly). Therefore it weighs (347452 x 0.92) = 319,655.84 (319.7T)

The wing area corresponds to "S" in the equation, which we know is 427.8m^2.

"p" (rho) corresponds to the air density, which we can calculate based on the atmospheric pressure and temperature given in the question.

"V^2" corresponds to the speed, we know the takeoff speed (looks like 376kmh).

So at this point, the lift equation equals the weight force of the aircraft and every other variable is known, so you just solve for the only unknown (the coefficient of lift, CL)

impossible to read (even enlarged version)

Oof well I quit have spent 5hrs seriously on these and only got 1 out of 3 done

[Regmorus]

Oh, that's long. But it's still impossible to read O_O

Ik can't ask another question tho it won't let me
