Resolve a vector of 50km at 215 into its y component .round answer to second decimal

Answer 1

Resolve 50 km at 215° into its x component:

$$V_x=50\text{ cos}215°=-40.96\text{ km}.$$

Resolve 50km at 215° into its y component:

$$V_y=50\text{ sin}215°=-28.68\text{ km}.$$

* We assumed that 215° is the angle counted from positive x-direction (215° counter-clockwise).
