A cow ambles through a break in the barnyard fence and wanders 34 m at 60.1° north of east, and then 21 m east. (a) What is the shortest path for the cow to return to the barnyard (include direction)?

(b) If the cow’s wanderings last 3.4 minutes, what is the cow’s average velocity?

(c) A branch falls startling the cow into a full-on 10.0 m/s trot. What acceleration did the cow experience if it took 20. meters to reach its maximum speed starting from rest?

(d) Assuming the cow's trot was in the direction back towards the barnyard, for how long must the cow maintain its maximum speed to return to its original starting position?
