Title: How do I add these vectors to find the magnitude and direction? Post by: Fireburns92 on Jan 27, 2013 Find the result of adding the following vectors.
A = 18.0 meters at an angle of 6.0° B = 5.00 meters at an angle of 165.° I thought I was doing it right, but I guess not cause everytime I checked it, it was wrong. Title: How do I add these vectors to find the magnitude and direction? Post by: mickabra on Jan 27, 2013 My personal favorite way to do this is breaking it up into sections. Here's how I would do it:
18cos6 + 5cos165 = 13.07176 18sin6 + 5sin165 = 3.17561 You then use Pythagorean theorem square root(13.07176)^2 + (3.17561)^2) = 13.451967 That is the length of the vector. to the find the direction you do: inverse tangent(3.17561/13.07176) = 13.6547 degrees Is that the answer you should be getting?
