Homework Statement
While vacationing in the mountains, you do some hiking. In the morning, your displacement is S-morning = (1600 m, east) + (3300 m, north) + (160 m, vertical). After lunch your displacement is S-afternoon = (1800 m, west) + (2000 m, north) - (350 m, vertical). At the end of the day, how much higher or lower (in m) are compared to your starting point in the morning?
Homework Equations
A^2 + B^2 = C^2
The Attempt at a Solution
I can't find any other relevant equations that is in the chapter and no examples are given with a third displacement value.
My attempt in the problem using the same method for both the morning values and after lunch values:
(1600)^2 + (3300)^2 = C^2
c = 3667.4 m
then...
(3667.4)^2 + (160)^2 = C^2
c = 3670.9 m
I used the same method for the afternoon values, found the difference between the two (1003.1 m), and it was the incorrect answer.
Thanks,
Daniel
