Two forces act on an object. The first force has a magnitude of 17.0 N and is oriented 68.0° counter-clockwise from the x axis, while the 2nd force has x- and y-components (-19.0 N, 16.5 N). Express the magnitude and direction of the net force.

  • physics - ,

    F(x) =17cos68-19 =
    F(y) = 17sin68+16.5 =
    F=sqrt{F(x)²+F(y)²}=
    tanα =F(y)/F(x)=
