Question

find the resultant mag and dir for the specified vectors pls

A
B
C
D
Observe the following vectors:
A. Construct an X-Y chart for all vectors:
X
15 cos(60°) = 7.5
10 (05(1909-0
28°
D=50
25 cos (90)=0
50 (os(28)=44.1
A+B+C+D
||R|| = 29
0 = 157° from x
(23° N of W)
60°
B. Find the resultant (mag and dir)of the following:
A = 15
A-C
B = 10
C = 25
15 sin(60) = 139
10 sin (90°) = (10
Y
25 sin (90) = 25
50 sin (28) = 23.5
||R|| = 38.7
0= 78.8⁰ from x
(78.8° N of E)
D + 2C
R = 51.4
0=211° from x
(31° S of W)
