The site from which an airplane takes off if the origin. The x-axis points east, the y-axis points straight up. The position and velocity vectors of the plane at a later time are given by:

r=(1.61*10^2i) m and v =+100i m/s

The plane most likely is____

a) ascending b) descending c) just touching down d) in level flight in the air e) taking off

2. Relevant equations

3. The attempt at a solution

Thought I could exclude C because it's greater than 0, but j isn't give and j could be 0. No idea what the correct answer is.
