Two forces 429 N and 591 N act on an object. The angle between the forces is 46°. Find the magnitude of the resultant and the angle that it makes with the larger force.
You can put this solution on YOUR website! Here is a representation of the two forces and their resultant, :
The rest is trigonometry.
You could use law of cosines and law of sines,
but I would favor just calculating the horizontal and vertical components.
The 429N force can be seen as the sum of
a horizontal component of magnitude , and
a vertical component of magnitude .
The 591N force an be seen as the sum of
a horizontal component of magnitude , and
a vertical component of magnitude .
Adding up components, you get the horizontal and vertical components, and --> . .
