Answer:
A= 61.35
B= -44.40
Explanation:
1. Using the components method we have:
Considering that the vector sum , then:
Then:
It means the value of x and y component is 0.
2. Determinate the equations that describe each component:
Form Eq. (1):
Replacing A in Eq. (2):
Replacing values of C, α and β in (4):
Replacing value of B in (3)
