Question

Vector A⃗ has magnitude 4.0m and points to the right; vector B⃗ has magnitude 3.0m and points vertically upward.

Answer 1

what's the question?

Answer 2

it asks for the direction of C counterclockwise from A

Answer 3

so what's the vector sum of the two?

Answer 4

it's 5

Answer 5

ok

Answer 6

that's the magnitude

Answer 7

i found the angle but it needs to be in 2 sig figs

Answer 8

so turn 5m into 2 sigfigs. Make the resultant vector "look" just like the vectors used to find it

Answer 9

so 5 is the angle?

Answer 10

its asking for the angle

Answer 11

no, 5m is the resulting straight line displacement. You've been given the legs of a right triangle. find the hypotenuse

Answer 12

and since you know the 3 sides of a right triangle, find the angle that the resultant vector makes with the horizontal axis.
