Best ResponseYou've already chosen the best response.2why do you think the asnwer is 25N ???

Best ResponseYou've already chosen the best response.1it looks pretty obvious.....doesn't it....do you want me to show you how i got it???

Best ResponseYou've already chosen the best response.2question 10N down 8N up how is that 18N down shouldn't it be 2N down?!

Best ResponseYou've already chosen the best response.1try to find the hypotenuse like that....

IrishBoy123

Best ResponseYou've already chosen the best response.2forget about hypoteneuses for the minute do you have a book answer if it is 18N down the answer is 32.33N if it is 2N as it should be the answer still isn't 25N do you know the law of cosines??? cos that makes this really easy

Best ResponseYou've already chosen the best response.2if the diagram is right, this is how you do it you must resolve the 17N force in the x and y directions

Best ResponseYou've already chosen the best response.1is it ....C^2 = A^2 + B^22abCos45???

Best ResponseYou've already chosen the best response.2yeah! do you actually know that law?!?! cos it makes life really easy this easy http://www.wolframalpha.com/input/?i=%2817%5E2+%2B+2%5E2++2%2817%29%282%29cos+135%29%5E%281%2F2%29

Best ResponseYou've already chosen the best response.1yah....well kinda...ok but please tell me under what scenario do i use the sin law in questions such as these......or do we ever use the sin law in these type of questions?

YumYum247

Best ResponseYou've already chosen the best response.1because i haven't done a single question that uses sin law instead of cos.

IrishBoy123

Best ResponseYou've already chosen the best response.2you need to know more angles to use the law of sines, though it is a much easier rule to apply look at this https://gyazo.com/75c2ae6ed28fa5e3109a4e87a4775967

Best ResponseYou've already chosen the best response.1ok Thanks hun.....just one last thing.....to find the angle, we use sinA/a + SinB/b = SinC/c right???????????/

YumYum247
 one year ago
Best ResponseYou've already chosen the best response.1i meant sinA/a = SinB/b = SinC/c

IrishBoy123

Best ResponseYou've already chosen the best response.2yes, that is the law of sines but the question does not want the direction of the force, just its magnitude

IrishBoy123

Best ResponseYou've already chosen the best response.2i think we shoukd just resolve the 17N force in the x and y direction as i suggested.

YumYum247

Best ResponseYou've already chosen the best response.1yah but for some reason, the examples that i have also include the angle.....so my final answer would be like....suppose 50N (E70S)

YumYum247

Best ResponseYou've already chosen the best response.1but i think in our case the angle would be 45degree right??????

IrishBoy123

Best ResponseYou've already chosen the best response.2we can do the angle but using simple trig id's did you follow the drawing hwere the 17N is resolved in x and y directions, cos that is a few steps off getting us done.

IrishBoy123

Best ResponseYou've already chosen the best response.2the final angle will not be 45deg

Best ResponseYou've already chosen the best response.2forgive me for the impertenance (!!!) but did you follow the resolving of the 17N

Best ResponseYou've already chosen the best response.217 cos 45 up, 17sin45 to the left

YumYum247

Best ResponseYou've already chosen the best response.1hey sorry, i went to take a d....p but yah so 17sin 45 will give me the angle on xaxis and 17cos45 will give me the angle on the yaxis????
