Homework Statement Vector A⃗ has a magnitude of 20m and makes an angle of 30∘ above the positive x axis. Vector B⃗ has a magnitude of15m and is oriented 60∘ to the left of the y axis. Find the magnitude of A⃗ −B⃗ . Find the direction of A⃗ −B⃗ . Homework Equations sin 150 = sin 30 = 0.5 cos...

Homework Statement In what direction is your friend from the starting point after skiing 3km east and then 1.5km north? Homework Equations angle = tan-1(1.5km/3km) = 26.6 degrees The Attempt at a Solution they want the answer in terms of degrees "north of east " not sure what the rules are...

Super clear ... thank you very much for your help.

Oh . I see. Thanks you . Magnitude can't be negative So is it -60 with respect to the x causes because it's now in the third quadrant since the vector b negative is when you reverse the head and the tail of the arrow.

Homework Statement If the vector B⃗ has a magnitude of 45.0 m and makes an angle of 60.0 ∘ with the +x axis, the vector -B⃗ choices: 1. has a magnitude of 45.0 m 2. has the same direction as B⃗ , but a magnitude of − 45.0 m 3.makes an angle of − 60.0 ∘ with the +x axis 4. has the opposite...
