Solve the Problem $t$ , Find the Body's Positios $\mathrm { t }$

Multiple Choice

Solve the problem.
-Given the velocity and initial position of a body moving along a coordinate line at time $t$ , find the body's positios $\mathrm { t }$ .
$v = \frac { 8 } { \pi } \sin \frac { 4 t } { \pi } , s \left( \pi ^ { 2 } \right) = 2$

A) $s = - 2 \cos \frac { 4 t } { \pi } + 4$
B) $s = - 2 \cos \frac { 4 t } { \pi } + 8.2134$
C) $s = 2 \cos \frac { 4 t } { \pi } + 4$
D) $s = - 2 \cos \frac { 4 t } { \pi } + 3.3073$ time
