(1 point) Let the velocity vector be v(t) = (6 cos(3t) , 5t*, 9 exp(3t) ) and the initial position vect be r(0) = (1, 3, 2) . Compute the position vector r(t) O A. (-18 sin(3t) , 20t3, 27 exp(3t)) O B. (2 sin(3t) , to, 3 exp(3t) ) + (1, 3, -1) O C. (2 sin(3t) , 15, 3 exp(3t) ) D. (18 sin(3t) , 20t, 27 exp(3t) ) | (1, 3, 2) O E. (2 sin(3t) , to, 3 exp(3t) ) + (1, 3, 2)
