Let ->V1= -6.1 ihat + 8.0 jhat and ->V2 = -4.8 jhat + 4.2 ihat.

Determine the direction of ->V1 counterclockwise from the +x direction

Determine the direction of ->V2
counterclockwise from the +x direction

  • physics -

    x is - and y is + so quadant 2
    tan theta = y/x = 8/6.1
    theta = 52.7 degrees up from -x axis
    so angle = 180-52.7 = 127.3
    Do the second one the same way

  • physics need to check -

    I get 131.18 degrees and its wrong. I don't know what I am doing wrong.
