Question

The figure shows four tracks (either half- or quarter-circles) that can be taken by a train, which moves at a constant speed. Rank the
tracks according to the magnitude of a train's acceleration on the curved portion. If multiple tracks rank equally, use the same rank for
each, then exclude the intermediate ranking (i.e. if objects A, B, and C must be ranked, and A and B must both be ranked first, the
ranking would be A:Greatest, B:Greatest, C:Third greatest). If all tracks rank equally, rank each as 'Greatest!

Expert Solution

Step 1

Given the four tracks that can be taken by a train which move from a constant speed.

The total acceleration depends upon the radius only bcoz the linear velocity of the train is constant. Thus the acceleration inversely proportional to the radius of path. The radius of the path R1 is smallest. Velocity is composed of a speed and direction, any process that changes the director must contain acceleration.
