The answer
<span>the third rope to counterbalance Sam and Charlie is F
and vectF +vectF1 +vectF2 =vect0
let's consider axis
y'y </span>vectF = -F
vectF 1= F1cos60
vectF 2= F2cos45
-F = -F1cos60-F2co45
so F= F1cos60+F2co45= 350x0.5+400x0.7=457.84 pounds
<h3>
Answer: choice B) counterclockwise rotation of 90 degrees around the origin</h3>
To go from figure Q to figure Q', we rotate one of two ways
* 270 degrees clockwise
* 90 degrees counterclockwise
Since "270 clockwise" isn't listed, this means "90 counterclockwise" is the only possibility.
