Multiple Choice

Find the vector v with the magnitude $\frac { 15 } { 2 } \text { and direction of } \mathbf { u } = \{ 18 , - 18,9 \}$

A) $\mathbf { v } = \left( 5 , - 5 , \frac { 5 } { 2 } \right)$
B) $\mathbf { v } = ( 5 , - 5,5 )$
C) $\mathbf { v } = \left( 9 , - 9 , \frac { 9 } { 2 } \right\}$
D) $\mathbf { v } = \left( \frac { 5 } { 2 } , - \frac { 5 } { 2 } , \frac { 5 } { 18 } \right)$
E) $\mathbf { v } = \left( \frac { 5 } { 18 } , - \frac { 5 } { 18 } , \frac { 5 } { 6 } \right)$
