Problem 3-9 - Vector sum - Part 3 (c)
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.
Accumulated Solution
| Variable | \(x\) comp | \(y\) comp |
|---|---|---|
| A | \(0\) | |
| B | ||
| C | ||
| Sum |
Correct!
The \(y\) component of \(\text{A}\) is (in \(km\)):
(A) \(20\)
(B) \(-20\)
(C) \(0\)
