4.58 "Helicopter Problem"

Does anyone know how to do this problem?

I tried it and I got 16819i, 0j, -3364k (all in Newtons) but says wrong
I thought it might be because of sig figs, so i tried 17000i, 0j, -3400k still wrong :/

I used m= 28032kg from the 2.75E5 N
Did someone who got this correct use the Newtons as mass and get it correct? or did you convert the Newtons to kg first, and then use as mass?

  1. That's exactly what I got, but you have to express the answer in the whole equation form, so it should be F=17000i-3400k, not separated by commas.

  2. oh my, thank you very much!!
    it says "express your answer in terms of i,j,k" so i thought the commas are required ^^
