Suppose a car is traveling at 55 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.

1. East: .
2. South: .
3. Southeast: .
