Best ResponseYou've already chosen the best response.0Suggest you use geometry. You have a right triangle with the hypothenuse as your force of 32 lbs. The gravity/(vertical component) would be sin 30 degrees x 32. The horizontal component will be cos 30 degrees x 32. =( sqrt of 3) x 16.

Best ResponseYou've already chosen the best response.0equation of force is F=fcos(theta)i+fsin(theta)j right?

Best ResponseYou've already chosen the best response.1That is the vector components yea, the i=<1,0> is the X direction, and the j=<0,1> is the y direction component

Best ResponseYou've already chosen the best response.1calculate each, Magnitude of F times cos(theta) for the x component, and magnitude of F times sin(theta) for the Y component

Best ResponseYou've already chosen the best response.0So then plugging numbers in we have: 34cos(30)i+34sin(30)j

Best ResponseYou've already chosen the best response.0simplifies to: 34(sq3/2)i+34(1/2)j

Best ResponseYou've already chosen the best response.1\[F _{Tot}=F _{x}i+F _{y}j\]

Best ResponseYou've already chosen the best response.1yes, just calculate Fx and Fy, those are the legs of the triangle, the components of the force

Best ResponseYou've already chosen the best response.0um then the answer will be: \[17\sqrt{3}i+17j\]

Best ResponseYou've already chosen the best response.0Yeah? but they don't accept that answer

Best ResponseYou've already chosen the best response.1The vertical direction (UP) is said to be negative, so that component will be negative

Best ResponseYou've already chosen the best response.0oh sorry, right right. I wrote it wrong in here but wrote it correct into the answer box :P they don't like it

Best ResponseYou've already chosen the best response.1yeah, that is the Force written in component form. Not sure how you are supposed to enter the answer though

Best ResponseYou've already chosen the best response.0hrm..yeah because that should be right and the example is written that way too.

Best ResponseYou've already chosen the best response.0Previous questions in this homework have also rejected anything that has i or j in it, i'll just ask my prof monday :) thanks!!
