Best ResponseYou've already chosen the best response.0how can we determine the magnitude of R and direction of R if there's no problem lol?

Best ResponseYou've already chosen the best response.0Nikolas Oman April 17 at 6:46pm best way to resolve each vector into perpendicular components. i = positive horizontal direction (to the right) j = positive vertical direction (up) A = 5 cos 65 i + 5 sin 65 j B = 5 cos 50 i  5 sin 50 j C = 5 cos 45 i  5 sin 45 j R = A + B + C = (5 cos 65 + 5 cos 50  5 cos 45) i + (5 sin 65  5 sin 50  5 sin 45) j R = 2.435 i  2.834 j Now use the Pythagorean Theorem to get the magnitude: Magnitude of R = √(2.435² + 2.834²) = 3.7 m Direction of R = arctan(2.834/2.435) = 229.3° ... so that's 49.3° south of west

Best ResponseYou've already chosen the best response.0no thats another problem. question is whats the magnitude and direction of R if vectors are: A 3m south of east B 3m north C 3m 30 degrees north east D 3m 50 degrees south west

Best ResponseYou've already chosen the best response.0remind me, In the previous problem, A = 5 cos 65 i + 5 cos65 j <  angles were given? or is that the general form

anonymous

Best ResponseYou've already chosen the best response.0how about for this problem?

Best ResponseYou've already chosen the best response.0A 3m south of east B 3m north C 3m 30 degrees north east D 3m 50 degrees south west

Best ResponseYou've already chosen the best response.0this is all that's given

anonymous

Best ResponseYou've already chosen the best response.0hmm, that means that you have to figure out the angles from the given

anonymous

Best ResponseYou've already chosen the best response.0B is easy, 3 m north , angle = 90 degrees

anonymous

Best ResponseYou've already chosen the best response.0hmm yea and A? 45 degrees?

anonymous

Best ResponseYou've already chosen the best response.0since they haven't given you the angles, yes you can assume that A = 45 degrees

Best ResponseYou've already chosen the best response.0and now? how much is R?

anonymous

Best ResponseYou've already chosen the best response.0all you've got to do is use the same way you've used in the previous question :) I think your prob was trying to figure out the angles? right?

anonymous

Best ResponseYou've already chosen the best response.0well it's not my homework :) it's my friends homework and I have no idea how to do it :)

Best ResponseYou've already chosen the best response.0so: i = positive horizontal direction (to the right) j = positive vertical direction (up) then we can say the following : A = 3 cos 45  3 sin 45 B = 3 sin 90 C = 3 cos 30 + 3 sin 30 D =  3 cos 50  3 sin 50

anonymous

Best ResponseYou've already chosen the best response.0now: R = A + B + C = (3 cos 45  3 sin 45 ) + (3 sin 90 ) + (3 cos 30 + 3 sin 30) + (3 cos 50  3 sin 50) = 0 + 3 + pi  4.23 = 1.912

Best ResponseYou've already chosen the best response.0R= 3 cos 45 + 3 cos 30  3 cos 50)i + (3 sin 45 + 3 sin 90 + 3 sin 30  3 sin 50)j

Best ResponseYou've already chosen the best response.0R = 1.76 i  3.32 j I might have some calculation mistakes, it happens ^_^

anonymous

Best ResponseYou've already chosen the best response.0\[R = \sqrt((1.76)^2 + (3.32)^2)\] = 3.74 m

Best ResponseYou've already chosen the best response.0can you calculate this for me please? R = (3 cos 45 + 3 cos 30  3 cos 50)i + (3 sin 45 + 3 sin 90 + 3 sin 30  3 sin 50)

anonymous
