Solution: Two workers pull horizontally on a heavy box, but
Chapter 1, Problem 1.59(choose chapter or problem)
Two workers pull horizontally on a heavy box, but one pulls twice as hard as the other. The larger pull is directed at 21.0 west of north, and the resultant of these two pulls is 460.0 N directly northward. Use vector components to find the magnitude of each of these pulls and the direction of the smaller pull.

QUESTION:
Two workers pull horizontally on a heavy box, but one pulls twice as hard as the other. The larger pull is directed at 21.0 west of north, and the resultant of these two pulls is 460.0 N directly northward. Use vector components to find the magnitude of each of these pulls and the direction of the smaller pull.
ANSWER:Step 1 of 2
Given,
The net force acting on the box,
The direction of the larger pull is
Let us assume that the larger pull is 
Thus,
The net force is given by,
Clearly, the x-component of the net force is zero.
Thus,
The negative sign indicates that the angle measured is in the clockwise direction. And as we used sine for the x-component, the direction of the smaller pull is
