4. When you take dynamics, you will use polar coordinates that have unit vectors to denote the radial (ê,) and transverse (ê) directions. This is a different coordinate system than a Cartesian coordinate system, but the unit vectors function just like unit vectors in Cartesian Coordinates (i, j, k). That is, the unit vectors define the direction of each axis. Determine the magnitude of the resultant of the forces. You can assume a counterclockwise angle from the axis is positive. Please leave your answer in variable form. Simplify your answer as much as possible.
