Question

A Fox is chasing a bunny. The bunny is initially hopping east at 6 m/s when it first sees the fox. Over the next half second the bunny changes its velocity to West at 11 m/s and escapes. What was the bunny’s average acceleration (magnitude and direction) during this half second interval? A Fox is chasing a bunny. The bunny is initially hopping east at 6 m/s when it first sees the fox. Over the next half second the bunny changes its velocity to West at 11 m/s and escapes. What was the bunny’s average acceleration (magnitude and direction) during this half second interval?

Explanation / Answer

Avg acc = change in velocity /time

Let east direction is positive.

So velocity final = - 11 (as v is in west)

Velo initially = 6

Acc = - 11-6/(1/2)

= 17*2 =34 m/s^2 in west
