1. A vector is 40.0 m long and makes an angle of 50.0° counterclockwise from the y-axis (on the side of the -x-axis). What are the x- and y-components of this vector?
2. Homework Equations
Sin = opp/hyp
Cos = adj/hyp
3. I tried solving for the x and y components of the vector by taking the -cos(50.0) 40.0m and came up with this= x-component: -25.7 and for the y component I took the sin (50.0) 40.0 m and came up with this = y-component: 30.6 m. However, these answers aren't correct and I don't understand what I am doing wrong. Could someone please explain exactly what I'm doing wrong.
