physics question

Answer 1

how would we calculate the resultant vector in red?

Answer 2

you have to take the 4 vectors and break them into the x and y components
and add all the x-components and add all the y-components

and then you can find the magnitude and the angle

Answer 3

do you understand? @Ahmad234

Answer 4

Oh, have a look at this -- https://cdn.numerade.com/encoded/df209437-f9f3-4191-b45a-f62f73e9c6dc.webm

Answer 5

@AZ I donot understand

Answer 6

??

Answer 7

I don't understand angles ? @AZ

Answer 8

thats sad

Answer 9

@Ahmad234

so
A = 100 m east
B = 300 m south
C = 150 m 30 degrees south from west
D = 200 m 30 degrees west from north

Answer 10

A only has an x-component
B only has a y-component





does that help?

Answer 11

you have to remember
sin 30 = opposite side / hypotenuse
we know the hypotenuse is 150
so

sin 30 = opposite side /150
and so
opposite side = 150 * sin 30

and the opposite side = y-component
and since it is in the third quadrant, the sin value will be negative

and similarly for the x-component, it would be cos
anad cos is negative in the second quadrant
