Unformatted text preview: What is the total distance traveled by the walker? What is the vector displacement of the walker during the walk? /fl_\ 7. A walker walks east for 1500 m, north for 1000 m and then northwest (midway ’ between north and west) for 750 m before stopping to rest. The walker walks at an average speed of 1.5 m/s. 8 What is the elapsed time for the walk?
