Chapter 1, Problem 1.11

(choose chapter or problem)

Consider two vectors described as follows: 1. A woman climbs 1.2 m up a ladder, so that her displacement vector is 1.2 m, upward along the ladder, as in Figure 1.12a. 2. A man is pushing with 450 N of force on his stalled car, trying to move it eastward. The force vector that he applies to the car is 450 N, due east, as in Figure 1.13a. What are the physical meanings of the vectors and ? (a) points upward along the ladder and has a magnitude of 1.2 m; points due east and has a magnitude of 450 N. (b) points downward along the ladder and has a magnitude of 1.2 m; points due west and has a magnitude of 450 N. (c) points downward along the ladder and has a magnitude of 1.2 m; points due west and has a magnitude of 450 N. Rea
