3. ### Given u=[1 2 1], v=[-2 3 2] and w=[4 -1 3], find a scalar k such that ku+v is perpendicular to w?

m = ku+v m = k{1,2,1} + {-2,3,2} m = {k-2, 2 k+3, k+2} vector m perpendicular to w if m • w = 0 {k-2, 2 k+3, k+2} • {4,-1,3} = 0 5 (k-1) = 0 k = 1

8. ### Is there a maximum to how big the K of a spring can be?

After k becomes to big, the force of streching the spring would break it. So yes, k could become too big depending on the material Assuming you meant the k in F=kx
