Thank you very much, I got it I did it like this: AC(11|4|5) = (cx-(-2)|cy-2|cz-3), then separated it in 3 simple equations: cx+2=11; cy-2=4; cy-3=5. And got C(9|6|8). Also, you kind of implied with your last post, that it could be measured with help of the vector's lenght, how?

It's length is as far as I know is |C|, 12.72, which is the measure of the diagonal

Oh man, thanks a lot, then I suppose I have to do the following: AB: (2-(-2)|10-2|4-3) AD: (5-(-2)|-2-2|7-3) Then AC: (4+7|8-4|1+4) Thus the C point is (11|4|5), right? But this is somehow wrong because when doing calculating CD or BC I get don't get 9! What am I doing wrong?

AB+AD would point in the direction of AC, but I don't know those vektors, I only know the points ABD I know how to perform certain operations with vectors, but as I said, I missed some classes, and probably the key to resolve this problem

This is what I mean I have also missed some classes, and that's why I require help from you

Oh Sorry, I meant AC = 12.78, since it's a square, BC and CD must be 9 too.

Homework Statement Show that there is a C point to these points A(-2|2|3), B(2|10|4) and D(5|-2|7), so that the quadrangle ABCD a square is. Determine the coordinates of C. The Attempt at a Solution All I have done is measure AC, CD and BC, which are 9, 9 and 12.78. But how do I get the C...

OK, I assume the figure might be a 90° triangle, with AB and AC being the cathetes. Let's suppose A: (1|1), B: (2|1) and C: (1|3), my question is, how do I get a vector out of this data?

Thanks a lot for your input, but could you please expand this a little more, I don't quite understand

Hello! I am preparing for an exam, I didn't really had much time for, and it would be nice of you if you could help me! Homework Statement Draw a figure, so that the following is true: (AC - AB) * AB = 0 2. The attempt at a solution Since I had to miss some classes, I don't really have...

Yes, I meant the coefficient. And also, the stop the car, you reduce the applied force to 120N I don't have the kinetic coefficient

Homework Statement A 1326kg car lies on a flat surface. To make it move very slowly (a~0), one needs a force of 160N parallel to the surface. To stop it, the force must be reduced to 120N. Homework Equations Calculate the friction forces of the car On Tuesday I have an exam regarding...
