I'm having trouble with the algebra of this word problem.
Resultant Force: Find the angle between the forces given the magnitude of their resultant. Force 1 is a vector in the direction of the positive x-axis and force 2 is a vector at an angle theta with the positive x-axis.
Force 1: 45 pounds
Force 2: 60 pounds
Resultant Force: 90 pounds
I'm stuck on solving for the resultant vector component using Force 2's vector component of,
Force 2 = w = 60<cos theta, sin theta>
Would you please write out every step along the way? I really need to learn this so I can pass my test on monday.
