I think it's 45-20 = 25s
Microgravity lasts 25s
On an imaginary parabol, the airplane will be twice at 9600
Hence, in between those two points, there is microgravity
You found at which time the plane will "cross" this 9600 line
So just get the time in-between those 2 positions
Idk if it makes sense
