Question

last question! help please, can't figure this one out

Answer 1

what's this, a test question?

Answer 2

no, homewoek

Answer 3

work*

Answer 4

well break up both vectors to I and J components

and add the components

Answer 5

how? i don't understand

Answer 6

well for example U is 22.9 units long aka magnitude

Point at 25.6 degrees

Its i component is 22.9*cos(25.6)

Its j component is 22.9*sin(25.6)

now do that for v and add the components

remember i component = magnitude * cos(theta)
j componen=magniture * sin(theta)

Answer 7

do same for v and get back to me :)

Answer 8

i = 41*cos(122) j=41* sin(122)

Answer 9

Yes also make sure your calculator is in degree mode not radians

you should get for
U= a*i + b*j
V= c*i + d*j
wher a, b, c, and d are constants
(a+c)*i this this is x component of U+V

(b+d)*j this is Y component of U+V

Answer 10

what is a b c d?

Answer 11

a*i is is x componen of U
Get by magnitude of U * cos (theta of v) = 22.9 * cos(25.6)
b is y component of U mag of * sin(theta of v

c is x comp of V
d is y comp of V
