So we denote force that small exert as x
that mean larger boat exerts 2x maganitude of force
Do you have a picture or diagram?
you can add your vectors to get the direction of motion..right?
as you can see, i added one vector to the end of the other, and where it ends up pointing is our new direction of travel
I stil don't understand.. how did it turn into a parallelogram? our teacher told us to use the position diagram and the vector diagram.. :S
vectors can move around the graph; they arent anchored to one spot
vectors are simply direction and magnitude with no regard to initial position....
we add vectors by stacking them head to tail and drawing a new vector from the start to the end...
it is, the initial positions are to the left and right of the ship; then i took one vetor and added it to the other to determine the direction of travel when both forces are applied
oh I understand now. So after I draw the parallelogram, what do I do?
well, that gives you an idea of whats going on; the real eat is in deciphering the angles for the information they can give...
one vector is twice the other, so we can use 1 and 2 as magnitudes....length of the vectors right?
so the length of the vectors represent tension?
the length represent force, whatever you wanna call it :)
oh ok. sorry for asking so many questions, I'm not good at vectors :/
lets start getting some sin and cos number to define these vector better....
vector small =
vector large = <2cos20, 2sin20> you see why?
vs=<.9659, .2588> vl = <1.8794, -.6840> now we add them like we did in the picture but this time its simply the numbers
Yes, i'm following
.9659, .2588 1.8794, -.6840 ------------- <2.8453, -.4252> is the direction and length of our new vector
we take the inverse tangent of these number to find the angle created....and hopefully its right :)
|-8.499| = 8.499 we good with it? do you see what i did ?
if theres another way to get to that, fine; but thats how id do it cause it works lol
Oh, I see. I get it now! thanks a bunch :D
