I came across the most tedious one I've seen a while ago. It continues for 2 more pages but I can't into taking screenshots like that.

easy

[eqn] F=ma [/eqn]

[eqn] 2.00\times 10^{4} = m \cdot 1020 [/eqn]

[eqn] \implies m = 0.051kg [/eqn]

That's a light aircraft op.

It's very easy to make up complicated equations: Try to solve a diophantine equation or a nonlinear PDE chosen at random and see if it is not the hardest problem you have ever seen.
Now, given the fact that our time on this earth is limited, we might as well spend our time on interesting questions.

It's used all the time in theoretical physics and there are attempts being made now to add an extra term that may be plausible at higher energies but with a mass scale factor that is extremely low.

It's change in potential. W=m*g*h

It's a gross understatement of calculating change in altitude. No standard atm, no nothing

Close but no...

KE=PE

Here PE can be stated as gravity.

PE(grav) = M*G*H

So...

2.00 x 10^8 J = M*(9.81m/s^2)(1020m)

(2.00 x 10^8 J)/(10006.2) = M

M = 19987.6 kg
