Simultaneous foul w/ bucket - what is POI?

[Mendy Trent]

A1 lets a 3-pointer fly. After it is in the air (A1 still an airborne shooter), B1 runs into him and U1 whistles a foul. At exactly the same time, U2 whistles a foul on A2 who knocked B2 to the ground while blocking out way too aggressively. The 3-point try by A1 is successful. U1 and U2 get together and decide that they have a simultaneous foul situation.

What is the POI? Do we shoot the FT with the lane cleared and then award the ball to team B regardless of the FT being made or missed? Or do we shoot the free throw with players on the lane (basically not penalizing the foul on A2 except for the additional team foul to Team A)?

Rule or Case reference please. Is it different for NCAA and NFHS?
