Question 11 A squirrel runs along an overhead telephone wire that stretches from the top of one pole to the next. The creature is initially at position x i = 2.89 m, as measured from the center of the wire segment. It then undergoes a displacement of Δ x = -5.03 m. What is the squirrel's final position x f in meters? Feedback:
