Vector A has magnitude of 40m at angel 225,if we want to add A to B so as to produce a resultant along the positive x-axis that has a magnitude of 20m,what must be the components of B
Answered by oobleck
A = <-40/√2,-40/√2>
so if v = <x,y> then
<-40/√2,-40/√2> + <x,y> = <20,0>
Answered by henry2,
R = 40[225o] + B = 20
40*cos225+(40*sin225)i + B = 20
-28.3 - 28.3i + B = 20
B = 48.3 + 28.3i.
