    Find Line Intersecting Line 1 & 2 at 90°: Vector, Parametric & Symmetric Eqs

    First of all thanks for responding, what I'm still sort of confused about is if I plugged those parameters into their respective equations i.e. [x,y,z] = [4,8,-1] + -1[2,3,-4] = [2, 5, 3] for line 1 [x,y,z] = [7,2,-1] + 1[-6,1,2] = [1, 3, 1] for line 2 would that mean that those aren't the...

    Cartesian vector application involving two forces.

    If I'm understanding this correctly, could I assume that Vx=0.6428F and Vy=0.7660F and use those directly in my (150 + vx)^2 + (0 + vy)^2 = 40000 equation or would I have to use Fcos(50) and Fsin(50) instead? Thanks for the help so far.

    Cartesian vector application involving two forces.

    Homework Statement Two forces act on an object at an angle of 50°. One force is 150 N. The resultant force is 200 N. Find the second force and the angle that it makes with the resultant.Homework Equations Ux=|U|cos(theta) Uy=|U|sin(theta) The Attempt at a Solution Basically I began by...

    Calculating Work and Initial Displacement with Cross Product

    Sorry, I didn't know how to include the triangle in the question so I just called it delta, but what I was having trouble with was finding the work to move from the initial displacement to the delta displacement. So basically I figured there was an initial displacement vector that I had to find...

    Calculating Work and Initial Displacement with Cross Product

    So if I multiplied [4, 7, 1]*[5,3,8] and got 49 as my dot product, then that's how much work is needed to result delta S = [5, 3, 8]? Why would they even mention the delta in the first place, because that's the only reason I assumed this question was difficult...

    Calculating Work and Initial Displacement with Cross Product

    Hey guys, I normally don't use forums for help but I've been stuck on these questions for some time now and I just want to see if there's anyone out there who can set me in the right direction. These questions are from a grade 12 Calculus and Vectors class and they relate to the cross product...
