1. The problem statement, all variables and given/known data
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 = 6.00 min), C (at t = 12.0 min), and finally D (at t = 18.0 min). Both axes are marked in increments of 1.50 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?
(b) Which has the greatest magnitude?
What is this average velocity in magnitude-angle notation?

2. Relevant equations

3. The attempt at a solution

Dont even know how to go about starting this problem someone please help me out.

OK. but what do you mean by magnitude-angle notation?

Not sure, thats what is asked for ....
the answer boxes look like this
[blank] m/s, [blank] ° (counterclockwise from the positive x axis)

The first thing you need to do is post the definitions of "magnitude" and "average velocity". The second thing is to try to use those definitions to answer the questions.

Why don't you split each movement into a parametric equation, x(t) and y(t). From this you can find each component of average velocity during the time interval; after that simply find the magnitude of the resultant vector.

I think it would also help if he posted his understanding of the terms "displacement" and "velocity."
