Question

(c3p 18-20) Vector A has magnitude of 5.0 at an angle of 60.0 o from the x-axis. Vector B has magnitude of 9.0 at an angle of-40.0 o from the x-axis. Let C=A+ B. Let D=A-B. Let V=2*A-B What is the x-component of vector C? Submit Answer Incorrect. Tries 1/10 Previous Tries what is the y-component of vector C? Submit Answer Tries 0/10 What is the x-component of vector D? Submit Answer Tries 0/10 What is the y-component of vector D? Submit Answer Tries 0/10 What is the x-component of vector V? Submit Answer Tries 0/10 What is the y-component of vector V? ubt Answer Tries 0/10

Explanation / Answer

1. Vector A = 5 cos 60 i^ + 5 sin 60 j^

= 2.5i^ + 4.33J^

vector B = -9 cos 40 i^ + 9 sin 40 J^

= -6.89i^ + 5.79J^

so, Cx = (2.5 - 6.89)

Cx = - 4.39

2. Cy = (4.33 + 5.79)

Cy = 10.12

3. Dx = ( 2.5 +6.89)

Dx = 9.39

4. Dy = (4.33 - 5.79)

Dy = -1.46

5. Vx = ( 2*2.5 +6.89)

Vx = 11.89

6. Vy = (2*4.33 - 5.79)

Vy = 2.87
