1. The problem statement, all variables and given/known data 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.
