Question

Suppose a car is traveling at 60 km/hr, and that the positive y-axis is north and the positive x-axis is east. Resolve the car's velocity vector (in 2-space) into components if the car is traveling in each of the following directions. The units are km/hr, but you do not need to enter units.
Southeast:
Northwest:

Answer 1

For the answer to the question above asking to resolve the car's velocity vector (in 2-space) into components if the car is traveling in each of the following directions. The units are km/hr, but
east: 60i + 0j 
south: 0i - 60j 
SE: (30√2)i - (30√2)j 
NW: (-30√2)i + (30√2) you do not need to enter units.
