1. The problem statement, all variables and given/known data

3. The attempt at a solution

Vch = Vce + Vhe Do I have this correct?

I am guessing I need to find the velocity of the carrier with the respect to earth, and also find the velocity of the helicopter with respect to earth. Than with these two answers I can find the velocity of the carrier with respect to the helicopter. Do I have this correctly?

You're on the right track.
Now try expressing $\vec v_\mathrm{CE}$ and $\vec v_\mathrm{HE}$ in terms of the given vectors.

By the way, your image is a bit large. Next time, can you make it a bit smaller (so it at least fits on a standard size screen) or upload it as attachment?

Here you go, I resized it. Sorry about that.

Ok so how does this look?

Vcw = Vce + Vwe which when numbers plugged in gives me 20 = Vce + 10. I ended up getting Vce = 17.3 m/h is that correct?

Vhe = Vha + Vae which when numbers plugged in gives me Vhe = 40 + 30. I ended up getting Vhe = 50 m/h am i correct or way off?

Thanks.
