Don't know how I found that could someone help me with the math?

2 - 1 = 1 m/s in the direction the faster car was traveling

Do maglev trains have zero friction?
Yes, there is friction from movement through the air. The higher the speed of the train and the greater the surface area of the train impacting the air, the greater the friction, and hence the temperature, energy loss and limitations on speed. In the future we will integrate this technology with zero/low pressure tubes, made from carbon fiber or some other materials that will allow these trains to operate with little to no friction and therefore unimaginable speeds, theoretically tens of thousands of miles per hour, and at a fraction of the energy required to lift an airplane from the ground and withstand friction and energy loss at super sonic speeds. These trains will likely be built underground for a number of reasons and likely begin by transporting freight.

Do boats have a high or low friction?
Boats usually have low friction (drag) compared to freight trains, but they have considerably more drag than most aircraft, especially the really fast ones. The faster the boat or aircraft, the lower the friction.
