Please answer part b of this question

You are to launch a rocket, from just above the ground, with one of the following initial velocity vectors: (1) v rightarrow 0 = 20i^ + 70j^, (2) v rightarrow 0 = - 20i^ + 70j^, (3) v rightarrow 0 = - 20i^ - 70j^, (4) v rightarrow 0 = - 20i^ - 70j^. In your coordinate system, x runs along level ground and y increases upward, (a) Rank the vectors according to the launch speed of the projectile, greatest first (b) Rank the vectors according to the time of flight of the projectile, greatest first.

Explanation / Answer

time of flight = 2*Vy/g

so more the y-component more will be flight, hence

so , 1 = 2 = 3 = 4
