Best ResponseYou've already chosen the best response.1okay, first can you give me what the problem says so i can depict the picture a little better?

Best ResponseYou've already chosen the best response.0A camera is suspended by two wires over a football field to get shots of the action form above. At one point, the camera is closer to the left side of the field. The tension in the wire on the left is 1500 N, and the tension in the wire on the right is 800 N. The angle between the two wires is 130 degrees. Determine the approximate magnitude and direction of the resultant force.

Best ResponseYou've already chosen the best response.0That says 50 degrees, i accidentally typed N

Best ResponseYou've already chosen the best response.1so the 800N is going directly East and the 1500N is going that 50deg direction?

Best ResponseYou've already chosen the best response.1okay so that means to get the component form you put <1500cos50, 1500sin50> and add that with <800, 0> **the sine is zero because it is on the xaxis.** and what do you get?

Best ResponseYou've already chosen the best response.0Why do you put <1500cos50, 1500sin50>

Best ResponseYou've already chosen the best response.1that should give you <1764, 1149> you have to sqaure them and set them equal to the resulant vector so R (being the resultant vector)....dw:1361221683792:dw

Best ResponseYou've already chosen the best response.1that is the formula you use in order to put the two vectors in component form. then once you do that, you have to take the square root of the numbers you get squared.

Best ResponseYou've already chosen the best response.1If you dont understand it, i recommend quickly looking over this site (only should take 5 minutes) and then come back and try to see if you understand anything more and if you have any questions i am happy to help! :) http://hotmath.com/hotmath_help/topics/magnitudeanddirectionofvectors.html

Best ResponseYou've already chosen the best response.0@ihatealgebrasomuch okay then what do i do with the R i get 2105.207

Best ResponseYou've already chosen the best response.0i dont get how you got thoses number from 1500N and 800 N

Best ResponseYou've already chosen the best response.1okay, that is the magnitude of the resultant vector, not all you have to do if find the direction which is tan^1 (sin/cos) or in this case 1149/1764 which ends up being about 33 degrees
