Problem 3-9 - Vector sum - Part 2 (b)

Find the magnitude and direction of the sum of the vectors \(A + B + C\) using the component technique. Assume two significant digits.
\(A = 20\; km\) north, \(B = 30\; km\) east, \(C = 50\; km\; 55 ^\circ\) west of north.

Correct!

We now require the sum \(\text{R = A + B + C.}\)
 
The length of the vector \(\text{R}\) is \(20 + 30 + 50 = 100\; km\)

True

False
