Two vectors A and B are added to give a resultant R. The components of A are Ax = -8.0 units and Ay = 6.0 units and the components of B are Bx= 1.0 units and By=- 1.0 units. What is the magnitude of vector R?

Respuesta :

Answer:

10.09 units

Explanation:

For the A

Ax = -8.0 units

Ay = 6.0 units

The resultant vector = Ra = [tex]\sqrt{A^2_{x} + A^2_{y} }[/tex]

Ra = [tex]\sqrt{(-8)^2 + 6^2 }[/tex] =  10 units

For B

Bx = 1.0 units

By = -1.0 units

The resultant vector = Rb = [tex]\sqrt{B^2_{x} + B^2_{y} }[/tex]

Rb = [tex]\sqrt{1^2 + (-1)^2 }[/tex] = [tex]\sqrt{2}[/tex] units

Adding these two vectors A and B together, magnitude of vector R is

R = [tex]\sqrt{R^2_{a} + R^2_{b} }[/tex]

R =  [tex]\sqrt{10^2 + (\sqrt{2} ) ^2}[/tex] = 10.09 units
