Question

how to find magnitude and direction of the vehicle​

Answer 1

Explanation:

Net east displacement:

-12 + 8 = -4

Net north displacement:

-5

Final position:

(-4,-5)

Distance from origin:

√[(-4)2 + (-5)2] km ≅ 6.40 km

Direction:

θ = tan-1(-5/-4) ≅ 231.34º counterclockwise from due East

Answer 2

draw a vector triangle. when you draw the horizontaland vertical component , you enter with a right Triangle .magnitude of the vector is equal to the hypotenuse of the triangle so you can use the Pythagorean theorem to calculate it .rearrange the Pythagorean theorem to calculate the magnitude
