You are to launch a rocket, from just above the ground, with one of the following initial velocity vectors: (1) , (2) , (3) , (4) . 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'.
