As you walk to class with a constant speed of 1.60m/s , you are moving in a direction that is 20.8∘ north of east.

Part A
How much time does it take to change your displacement by 22.0m east?

Part B
How much time does it take to change your displacement by 31.0m north?

  1. distance = rate * time :)

    speed east = Ve = 1.60 * cos 20.8
    speed north = Vn = 1.60 sin 20.8

    time east = 22/Ve

    time north = 31/Vn
