Question

You are to launch a rocket, from just above the ground, with one of the following initial velocity vectors: (1) V initial= 20i +70j (2)V initial= -20i + 70j (3)V initial = 20i - 70j (4) V initial = -20i-70j. In your coordinate system, x runs along level ground and y increases upward.

In the following questions, you will need to rank these vectors. If multiple vectors 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 vectors rank equally, rank each as '1'.

Explanation / Answer

The given vectors V1 = 20i + 70j                             V2 = -20i + 70j                             V3 = 20i - 70j                             V4 = -20i -70j   The magnitude of the given vectors all are same so all have same vectors then V1:1,V2:1,V3:1,V4:1 But each vector in different coordinate.
