Problem 3-9 - Vector sum - Part 6 (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 | \(0\) | \(+20\) |
| B | \(30\) | \(0\) |
| C | \(-50 \cos 35^\circ\) | |
| Sum |
Correct!
The \(y\) component of \(\text{C}\) (in \(km\)) is:
(A) \(50 \cos 35^\circ\)
(B) \(50 \sin 35^\circ\)
(C) \(-50 \cos 35^\circ\)
(D) \(-50 \sin 35^\circ\)
