Question

You walk 20 m south and then 20 m east. Find the magnitude and direction of the resultant displacement.

a. 40.2 m south east
b. 37.4 m south west
c. 28.3 m south east
d. 16.5 m south west

Answer 1

I got C.

if you use the pythagorean theorem, 20^2 (400)+ 20^2(400)= 800. Then the square root of 800 is 28.28 which rounds up to 28.3. Hope this helps!!
