The figure below gives the path of a squirrel moving about on level ground, from point A (at time t = 0), to points B (at t = 4.00 min), C (at t = 8.00 min), and finally D (at t = 12.0 min). Both axes are marked in increments of 5.00 m (therefore the diagram is not drawn to scale). Consider the average velocities of the squirrel from point A to each of the other three points.

(a) Of the three average velocities, which has the least magnitude?

What is this average velocity in magnitude-angle notation?
m/s, ° (counterclockwise from the positive x axis)

(b) Which has the greatest magnitude?

What is this average velocity in magnitude-angle notation?
m/s, ° (counterclockwise from the positive x axis)
