A toy freight train consists of an engine and three identical cars. The train is moving to the right at constant speed along a straight, level track. Three spring scales are used to connect the cars as follows: spring scale A is located between the engine and the first car; scale B is between the first and second cars; scale C is between the second and third cars. Ignore the weights of the scales. If air resistance and friction are negligible, the relative readings on the three sping scales A, B, and C are the same. What are the relative readings of scales A. B, and C?
