Question

The clearest most thourough explination will be rated 5 stars thanks

In a "coasting race," two cyclists cross a starting line on a horizontal track with the same initial speed. They are about the same size, and are wearing the same type of clothing, so we can assume that they each experience the same air drag. Cyclist A is observed to slow down to a stop more quickly than Cyclist B. Assuming negligible friction with the road, and that neither cyclist does any pedaling, how can you account for the observation that A slows down more quickly than B? Explain your answer by applying Newton's 2nd law.

Explanation / Answer

Though Both 'A' and 'B' crosses a line with same speed suggest that their velocity were same but their accelaration may be different. In this case accelaration of 'A' in negative direction (i.e. Deaccelaration) is higher than that of 'B'. Hence 'A' slows down quickly. One must not confuse the velocity with accelaration.
