Problem 3-9
Find the magnitude and direction of the sum of
the
vectors A + B + C using the component
technique. Assume
two significant digits.
A = 2 km north, B = 30 km east, C
= 50 km 55° west of north.
We have 3 vectors referred to the directions N,
S, E, W and we must choose a set of coordinate axes. Of course any x, y
set will do but which of the selections below would provide the
simplest
solution?
