Exhibit 3-2

a Child Starts at One Corner $2 \hat { \mathbf { i } } + 2 \hat { \mathbf { j } } + 2 \hat { \mathbf { k } }$

Exhibit 3-2

A child starts at one corner of a cubical jungle gym in a playground and climbs up to the diagonally opposite corner.The original corner is the coordinate origin,and the x,y and z axes are oriented along the jungle gym edges.The length of each side is 2 m. Use this exhibit to answer the following question(s) .
-Refer to Exhibit 3-2.The child's displacement is:

A) $2 \hat { \mathbf { i } } + 2 \hat { \mathbf { j } } + 2 \hat { \mathbf { k } }$
B) $2.8 \tilde { \mathbf { i } } + 2.8 \tilde { \mathbf { j } } + 2 \tilde{ \mathbf { k } }$
C) $2 \tilde { \mathbf { i } } + 2 \tilde { \mathbf { j } } + 2.8 \tilde{ \mathbf { k } }$
D) $2 \tilde { \mathbf { i } } + 2 \tilde { \mathbf { j } } + 3.5 \tilde{ \mathbf { k } }$
E) $3.5 \hat { \mathbf { i } } + 3.5 \hat { \mathbf { j } } + 3.5 \hat { \mathbf { k } }$
