Textbook Question
Chapter 4, Problem 3PCE
As you walk to class with a constant speed of 1.75 m/s, you are moving in a direction that is 18.0° north of east. How much time does it take to change your position by (a) 20.0 m east or (b) 30.0 m north?

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 37 m to the north, then turn 61° to your right and walk another 45 m. How far are you from where you originally started?
A bird flies 100 m due east from a tree, then 200 m northwest (that is, 45° north of west). What is the bird’s net displacement?
