From t = 0 to t = 4.03 min, a man stands still, and from t = 4.03 min to t = 8.06 min, he walks briskly in a straight line at a constant speed of 2.70 m/s. What are (a) his average velocity vavg and (b) his average acceleration aavg in the time interval 1.00 min to 5.03 min? What are (c) vavg and (d) aavg in the time interval 2.00 min to 6.03 min?

![The figure gives the path of a squirrel moving about on level ground, from point A (at time t = 0), to points B (at t = 5 min), C (at t = 10 min), and finally D (at t = 15 min). Consider the average velocities of the squirrel from point A to each of the other three points. Of them, what are the (a) magnitude and (b) angle of the one with the least magnitude and (c) the magnitude and (d) angle of the one with the greatest magnitude? Give the angles in the range (−180∘, 180∘] (a) Number Units (b) Number Units (c) Number Units (d) Number Units](https://www.doubtrix.com/uploads/editor/0905118326zZjCRKnFCQ.png)
