<![CDATA[Car on a conveyor belt]]>A car is standing on a roadway that can move (some sort of band conveyor). The car moves in one direction, while the conveyor moves in the opposite direction. This conveyor has a control system that tracks the <u>cars speed</u> via radar and tunes the speed of the conveyor to be exactly the same (but in opposite direction).

The question is:

Can the car drive off the end of the conveyor or not?

(Sorry, but I want to see how many get this one wrong too)

and since the car is going 0mph the belt would not be moving and the car would be able to drive off at 1mph??? or not

but at the time the car would go 1mph the conveyor would move and then the radar would read zero. than 2mph the conveyor 2mph and so on. with conveyor at perfect reaction the car would stay on conveyor.??? maybe?

More information needed to come to a conclusion.

If this conveyor belt experiment is left unmanned, computer-controlled, in a walmart parking lot, and takes in excess of four minutes, how many abandoned shopping carts will the car hit?

Sorry Scott...

What kind of car? How many miles? Last oil change?

If the radar shows the car traveling at 10 mph, the belt would be moving at 10 mph... meaning that the car is traveling 20 mph according to the tachometer.

I dont even want to think about what would happen from a standstill.

Is the belt driven by a separate motor? if it is driven by the movement of the tires it would act like a Dyno. The car's tires would spin without moving the vehicle forward at all.

In order for the radar to ever read above 0 their would have to be some sort of horizontal movement. As soon as the belt reacted by matching the cars speed the car would stop moving relative to the ground, causing the car to once again move relative to the ground.

I am going to go with yes, because whenever the conveyor is spinning at the same speed as the cars wheels, the car will be not moving, thus the conveyor is at 0 but the cars wheels are still going, until the car moves then the conveyor would start to move again. It is very hard to explain for me but yes, the car would be able to move forward.

It depends if the person holding radar gun is mounted on solid earth, or if he's on the conveyor belt.

The radar will not compensate fast enough or the conveyor will max out.
