A wheel spins on a horizontal axis, with an angular spped of 140rad/s and with its angular velocity pointing east. Determine the magnitude of the angular velocity after an angular acceleration of 35 rad/s^2, pointing 68 degress west of north, with a time of 4.6 seconds. I found that the magnitude of the angular velocity is 61 rad/s, but how do i determine the direction of its angular velocity west of north in degrees.

I do not understand what you mean by
"The direction tangent can be obtained from the ratio of the components."
"The direction tangent can be obtained from the ratio of the components."
arctan (West component)/(North component) = angle west from north
The west component is the negative of the east component
The west component is the negative of the east component
