1. A girl walks 60. m due south, then 100. m due east, then 150. m due
north. (a) What is her displacement from her original position? (b) What
is the total distance walked by the girl? (c) In which direction should
she walk to return to her starting point in the least amount of time?
Express your answer in terms of the compass directions (north, south,
east, and west)

While exploring a cave, a spelunker starts at the
entrance and moves the following distances in a hori-
zontal plane. She goes 75.0 m north, 250 m east, 125 m
at an angle u 5 30.0° north of east, and 150 m south.
Find her resultant displacement from the cave
entrance. Figure P3.21 suggests the situation but is not
drawn to scale.
You walk 60 meters to the North and 60 meters to the West. Find the magnitude, direction, and sense of the resulting displacement, both graphically and algebraically.
