Vector a⃗ points in the positive y direction and has a magnitude of 12 m. vector b⃗ has a magnitude of 33 m and points in the negative x direction. find the direction of a⃗ + b⃗ . find the magnitude of a⃗ + b⃗

vector A has magnitude 12 m and direction +y

so we can say

vector B has magnitude 33 m and direction - x

Now the resultant of vector A and B is given as

now for direction of the two vectors resultant will be given as

so it is inclined at 160 degree counterclockwise from + x axis

magnitude of A and B will be

so magnitude will be 35.11 m

nah.   i'm just sleepy.

this is poiselle's equation from fluid mechanic in physics. mech eng
