Question

please help with...

Answer 1

Just add the components of all of the vectors to find the resultant displacement.
First he moves 2.6 km north, then he moves 4 km east then he moves 3.1 km north east.

Answer 2

Okay Nath what is it about this problem that is confusing to you?

Answer 3

The first displacement he moves 2.6 km but he has no horizontal displacement.
The second displacement he moves 4 km which is all horizontal.
The third displacement he moves 3.1 km which is only part horizontal (You should be able to figure out the horizontal component from the last post)

Answer 4

x=5.7 cos(45) i added the 2.6 to 3.1

Answer 5

Not quite.
For the x component 2.6 wouldn't be a part of it because none of it is in the x direction

Answer 6

you mean that 3.1 is not completely horiziontal

Answer 7

Yes. Also, the component that is 2.6 km is all in the y direction so none of it will be on the x component

Answer 8

so what do i have to do
