Question

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.

Answer 1

I answered this already

Answer 2

I do not understand what you mean by

"The direction tangent can be obtained from the ratio of the components."

Answer 3

arctan (West component)/(North component) = angle west from north

The west component is the negative of the east component
