Still doesn't mean it can accelerate quickly enough to reach minimum takeoff speed before the runway runs out though
I realise this is massively going against the spirit of the question
Jeez now people are losing the ability to understand English never mind maths and physics.
So - the only possible explanation is that it is impossible somehow for the wheel speed to match the speed of the conveyor. Something has to give - and it cannot be Newton's laws, so it has to be the other element in the equation.
Also chips are "Plant-based" no matter how you cook them.
The belt would speed up in an attempt to prevent the plane from travelling forwards, until such a point is reached where the friction generated by the speed of the belt travelling backwards precisely negates the thrust generated by the engines.
Should such an equilibrium be unreachable, the belt will continue to speed up to infinite speed, at which point the thought experiment terminates, before the plane is allowed to take off (or even start to move).
Of course it can, but within the rules it can't. Rather than think about take-off think about the initial moment.
Arrrrrrrggggghhhhhhh!!!!

What bit are you struggling with?
Drag race car on the start line (rear wheel drive obvs). Needs to maximise traction so applies the front brakes and spins the rear wheels to warm up the tyres. Car goes nowhere
So what speed are the wheels doing. Obviously the front wheels are moving at zero velocity. Are the rear wheels moving ?
No of course not. They are rotating, not the same as moving. They have zero velocity. They are however able to rotate whilst not moving. In this case its because they lost traction. In the case of the aircraft its because theres a moving conveyor under them. At no point do the aircraft wheels lose traction therefore their peripheral speed is identical to the speed of the conveyor. However the velocity of the wheel, (at the axle relative to the ground), can be different to both the peripheral speed (i.e. the rotational speed) and the conveyor speed.
Forgive the repetition...
