The Answer of $\text { For the curve } r ( t ) \text {, write the acceleration in the form aTT } + \text { anN. }$
-$$\mathbf { r } ( \mathrm { t } ) = \left( 8 \sin \frac { 5 } { 8 } \mathrm { t } + 8 \right) \mathrm { i } + \left( 8 \cos \frac { 5 } { 8 } \mathrm { t } - 3 \right) \mathrm { j } + 12 \mathrm { tk }$$
A) $a = \frac { 25 } { 8 } T$
B) $a = 25 T + 25 N$
C) $a = T + 25 N$
D) $\mathbf { a } = \frac { 25 } { 8 } \mathbf { N }$
