If a plane is traveling at takeoff speed on a conveyor belt and the belt is matching that speed in the opposite direction can the plane take off?
Yup.
You're right to note, that the speed of belt is matching the takeoff speed (some trolls forget about speed being relative). So the plane will take off, with it's wheels on the belt spinning twice as usual.
((Yes. The logical error that "catches" many people is that they are more familiar with cars than planes. A car exerts its forward force on the ground, like a person does. When you put them on a treadmill travelling backward at the same speed that the object is attempting to move forward, then they are attempting to move against an equally moving medium. This results in a Red Queen scenario and a stationary object.
A plane however, does not move forward using its wheels. They are freespinning objects independent of the propulsion system. A plane is exerting its forward force against the AIR, and therefore will move with respect to the air. A plane attempting to lift off on a conveyor belt (no matter the speed of the belt) will do so essentially just as easily as it would had it been running on a standard runway.
Mathmatically, this can be expressed by the fact that stationary objects are stationary because the forces are equal on all sides. A pencil resting on a table is exerting its force (as its weight) against the table, and the table is pressing back with equal force. When an object is moving on a surface (like a car or a grounded plane), frictional force is applied to the object resisting the forward motion. To calcuate the magnitude of this resisting force, you must multiply the normal force (the weight of the object), by the coefficient in friction (the calcuated "roughness" of the surface).
This leaves no variable for the speed of the surface below it to apply in order to counteract the thrusting force caused by the pushing of the air. This resisting force for the plane will remain essentially the same regardless if it is on a standard runway, a belt moving at 25 mph, or a belt moving at mach 3. As long as the wheels remain intact, the plane will take off. The only physical difference that the plane will experience in this scenario is that the wheels will move twice as fast. Half of the speed are caused by forces that are driving the plane forward, and the other half of the speed are caused by the conveyor belt moving backward.
A simple experiment that can prove this is demostrated on YouTube at the following link: http://www.youtube.com/watch?v=4owlyCOzDiE
It clearly demostrates that the speed of the belt has no bearing on the aircraft's ability to move. Once the craft overcomes the frictional force that would be present even with a stationary runway, no more force is needed, even as the author of the video ramps up the speed of the treadmill by several factors without compensating with the thrust.
Ergo a conveyor belt, matching the plane's speed or not, is completely impotent to hinder the aircraft's ability to take off.))
What else can I help you with?
Can a bus change direction of its velocity when traveling with constant acceleration?
Yes, a bus can change the direction of its velocity when traveling with constant acceleration. This change in velocity can occur when the bus is accelerating in the opposite direction to its initial velocity. The bus will slow down, stop, and then start moving in the opposite direction.
In what direction does a bus travel if it runs opposite northeast?
If a bus runs opposite northeast, it would be traveling south southwest.
What is the velocity of a car traveling backwards?
The velocity of a car traveling backwards would be negative, as it is moving in the opposite direction of its positive reference point.
Identify the force that keeps a box from sliding down an angled conveyor belt that slopes upward?
The force that keeps a box from sliding down an angled conveyor belt that slopes upward is friction. Friction acts in the opposite direction of the box's movement, preventing it from sliding down the slope.
What happens to the direction of light in which it travels during reflection?
During reflection, the direction of light reverses. If light was traveling towards a reflective surface at a certain angle, it will bounce off the surface at an equal angle but in the opposite direction.
What can proceed in the opposite direction?
Traffic, a conveyor belt, a river current, and a moving walkway can proceed in the opposite direction.
Do white lines separate traffic traveling in opposite direction?
yes
White lines separate traffic traveling in opposite directions?
yes
What happens if Something is traveling at constant deceleration?
It slows to a rest and then starts moving in the opposite direction at constant acceleration in that direction.
How does the force of friction act relative to an object in motion?
It will USUALLY pull the object backwards, in relation to the direction of the motion. This assumes that the material with which it has friction, moves slower than the object you are considering. However, if you put material on a conveyor belt, the force of friction, of the object with the conveyor belt, will pull it FORWARD until the object has the same speed as the conveyor belt.
Can a bus change direction of its velocity when traveling with constant acceleration?
Yes, a bus can change the direction of its velocity when traveling with constant acceleration. This change in velocity can occur when the bus is accelerating in the opposite direction to its initial velocity. The bus will slow down, stop, and then start moving in the opposite direction.

The velocity of a car traveling backwards would be negative, as it is moving in the opposite direction of its positive reference point.
Is it true or false that White lines separated traffic traveling in opposite direction?
That is false. At least in America. Solid yellow lines are the means to separate traffic traveling in an opposite direction. A solid white line marks the outside edge of your lane, or the outside edge of the lane traveling in your direction. Meaning you'll either go into the shoulder, or off the road entirely, if you go over the solid white line.
How do you reverse conveyors on papa louie?
To reverse conveyors in Papa Louie games, you typically need to interact with specific switches or buttons located near the conveyor belts. Look for any mechanisms that allow you to change the direction of the conveyor. Once activated, the conveyor will start moving in the opposite direction, allowing you to manage the flow of ingredients and dishes more effectively. Ensure to plan your movements accordingly to keep up with the order demands!

The force that keeps a box from sliding down an angled conveyor belt that slopes upward is friction. Friction acts in the opposite direction of the box's movement, preventing it from sliding down the slope.
Are vehicles traveling in the opposite direction of school buses that have stopped to unload children on a divided highway with dividing barrier required to stop?
No.
