Calculate the direction (angle with respect to the positive x axis)of a vector whose x and y components are 6 m and 11 m respectively. (1 point)A. O 28.61 degB. 061.39 degC.19.993 degD.22.772 degE. O 46.154 deg13. Calculate the magnitude and direction (with respect to the positive x axis)10

Answer 1

11.

x component = -4

y-component = -5

R = resultant

R^2 = x^2 + y^2

`R=\sqrt[\placeholder{⬚}]{(-4)^2+(-5)^2}`

Answer: R= 6.403 m (option D )
