For the displacement vectors a=(3.0m)i+(4.0m)j and b=(5.0m)i+(-2.0m)j, gave a+b in(a) unit vector notation and as a magnitude and an angle (related to i) now give b-a in unit-vector notation and as magnitude and an angle

Part (a) a + b = (8.0i - 2.0j) and from the x-axis

Part (b) b - a = (2.0i - 6.0j) and from the x- axis

Explanation:

Given,

From the addition of the two vectors,

Let be the angle of the resultant vector of the addition of the vectors with the x-axis (i).

Part (b)

From the subtraction of the two vectors,

Let be the angle of the resultant vector of the addition of the vectors with the x-axis (i).
