Three forces that act on a particle are given by F1 = (20i - 36j + 73k) N, F2 = (- 17i + 21j - 46k) N, and F3 = (-12k) N. Find their resultant vector. Also find the magnitude of the resultant to two significant figures.

Solution:
Three forces that act on a particle are given by F1 = (20i - 36j + 73k) N, F2 =
