(b) The new direction of 5dGis the same as the old: south. The vector 2.0d−Gcan be written as ˆ2.0(6.0 m) j.d−=G(c) The absolute value of the scalar factor (|−2.0| = 2.0) affects the magnitude. The new magnitude is 6.0 m. (d) The minus sign carried by this scalar factor reverses the direction, so the new direction is ˆj+, or north.
