lectric and JBorgen are right. Itīs impossible to build such a coveyor belt.

Conveyor belt speed must equal the wheel speed, according to this problem.

Those two speeds can only be equal when the air speed of the plane is 0.

Once the engines start up, the air speed will be greater than 0, which means the wheels must turn faster than the conveyor belt.

So the only way the conveyor belt can match the speed of the wheels is when everything is stationary (belt speed, wheel speed, and air speed all must equal 0). The plane will fly, but itīs impossible for the belt to match the wheel speed.
