With the jet. The treadmill will have no effect on the plane other than providing friction on the tires. The wind moving over the wings is what makes it lift off. If the jets can get the wind moving at the necessary speed, the plane will take off straight up until the wheels are off the ground. Then it will shoot forward like a SOB.


As for the truck, reading it again, it could be a semantic battle, since he said the truck carrying that stuff weighed that much, it could be read as this is the weight of just the truck, or it could be read as the weight of truck and cargo.

And since the weight is determined by mass and gravity, the truck would weigh less when they took flight because even though the weight is all still contained, the mass of the birds is not acting on any other participants since they are in the air.

Most people are 1/4" taller at the equator than at the poles due to centrifugal force of the earth spinning.

Wouldn't change anything. It'* still not the wheels that drive the plane...

Yes it would take off because the the thrust of the airplane is not being exerted through the wheels.

I still say with the treadmill moving backwards at the same speed what ever is powering it to move forward. will not cause it to lift.
it needs the air to move under the wings to create the initial lift. if it is not moving. there is no air to do so.

Take it away boys and girls...
reading the question again. No mention of a jet. no matter. even if the runway is moving backwards as the throttle is applied, the plane is still going to move forward. The only thing the treadmill is doing, is going to increase the wheel speed to twice what it would have been. That is the only affect it will have. the prop will still pull the plane forward no matter how fast the wheels are moving backwards

The plane will take off. If you don't believe the plane will take off, either build a model and try it, or take a class about kinetics
