2) We are watching a fox in a field. It begins to chase a rabbit and runs according to the position vector: r = (4t-5)i + 7j+(6t²-3t+9)k. a) What is the fox's position vector at t = 2 seconds and how far is it from us if we are the origin of the coordinate system? b) What is its velocity vector as a function of time, and what is its speed at t = 2 seconds? (Poor rabbit.... L) c) Is the fox accelerating (yes or no and why)?
