Question

Figure 4-21 shows the path taken by a skunk foraging for trash food, from initial point i. The skunk took the same time T to go from each labeled point to the next along its path. Rank points a, b, and c according to the magnitude of the average velocity of the skunk to reach them from initial point i, greatest first. If multiple points 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:1, B:1, C:3). If all points rank equally, rank each as '1'.

Explanation / Answer

Pls ignore earlier answer avg velocity = (displacement from initial position to final position)/time displacement from i to a = 1 unit displacement from i to b = 1 unit displacement from i to c = 3 units let t be the time taken to travel each part. so A = 1/t B = 1/t C = 3/t so ranking is as follows: C:1, A:2, B:2
