A fox is chasing a bunny. The bunny is initially hopping east at 9 m/s when it first sees the fox. Over the next half second the bunny changes its velocity to west at 13 m/s and escapes. What was the bunny's average acceleration (magnitude and direction) during this half-second interval?
What equation is used and how is this set up?
I've tried drawing this and I have figured out 22m/s2
and he is heading west but the 22 was wrong do I need to do something
with the half second?
