alright, here is the question and how far i got.
A light plane is traveling at 175km/h on a heading of N8[degree]E in a 40km/h wind from N80[degrees]East. Determine the planes ground velocity
im going to skip the notations so..
planes velocity relative to the air is (175cos8, 175sin8)...
hello, can someone please tell me if this is correct? no it is not for my homework.
place vector symbols above all letters.
|m-n| = |n|-|m|
place vector symbols about the letters to specify they are vectors
so are they the same?
ok
i know that the ho reamains the same but i don't know how i can show the relation between both cases? i don't understand how to get the ratio.
edit: here is what i did..tell me if it is right
case1
hi/ho = 0.050025012/100
hi/ho = 0.0005052012
case2
hi/ho = 0.05005005/50
hi/ho =...
