Some Physics questions

[From: ] [author: ] [Date: 11-05-06] [Hit: ]
B = 100 km, 67° north of west.C = 150 km,D = 200 km,What is the Value of Ax, Bx,......
Here, too make this thing easier, I'll write down everything given to us.

Refer your answer to the following questions on the problem below.

Add the following vectors:
A = 200 km, 30° north of east.
B = 100 km, 67° north of west.
C = 150 km, towards west
D = 200 km, 37° east of south

What is the Value of Ax, Bx, Cx, Dx and Ay, By, Cy, Dy?

What is the value of the summation of X?

What is the value of the summation of Y?

What is the magnitude of the resultant vector?

What is the angle of the resultant vector?

What is the quadrant of the resultant vector?

Refer your answer to the following questions on the problem below.

X-component = distance * cos θ
Y – component = distance * sin θ
Resultant = [(Sum x)^2 + (Sum y)^2]^0.5
Angle = Inverse tangent of (Sum y) / (Sum x)

When you add vectors components, you must know the direction. So let’s say East = +x, West = -x, North = +y, South = -y.

Add the following vectors:
A = 200 km, 30° north of east.
x = +200 * cos 30
y = +200 * sin 30

B = 100 km, 67° north of west.
x = -100 * cos 67
y = +100 * sin 67

C = 150 km, towards west
x = -150

D = 200 km, 37° east of south
x = +200 * cos 37
y = -200 * sin 37


What is the Value of Ax, Bx, Cx, Dx and Ay, By, Cy, Dy?

What is the value of the summation of X?

What is the value of the summation of Y?

What is the magnitude of the resultant vector?

What is the angle of the resultant vector?

What is the quadrant of the resultant vector?
