Homework Statement
Two snowcats in Antarctica are towing a housing unit north, (an example is shown in Figure 4-50 on page 102). Snowcat A pulls at an angle 49 o west of north, and snow cat B pulls at an angle 31 o east of north. The sum of the forces FA and FB exerted on the unit by the horizontal cables is north, parallel to the line L, and FA= 4633 N. Determine FB, and determine the magnitude of FA+FB.
2. Homework Equations
∑F=ma
The Attempt at a Solution
FA=4633N at 49
FB= xN at 31
FB(sin Θ)=FA(sin Θ)
FB(sin 31)=4633(sin49)
FB=4633(sin(49)/sin(31))
FB=6789
FB + FA=4633 + 6789
=11422
FB=6789
FB+FA=11422
My physics homework is online and requires me to plug the numbers in before automatically grading them. I plugged in 6789 and the answer was correct, however 11422 was wrong? Where did I mess up?
