Homework Statement
A car travels 8 km E, then 8 km N, thrn 16 km W. What is the car's displacement?
Homework Equations
a^2+b^2=c^2
The Attempt at a Solution
R^2=8 ^2+8^2
R=11.3 km.
The resultant, R, seems to be 11.3, but I don't think this is the final answer, because I haven't take the 16 km into account yet. What's the next step?
Thanks in advance for a reply!
