<span>Remember::
a) velocity is the first derivative of the position vector
b) acceleration is the second derivative of the position vector or, what is the same, the first derivative of the velocity vector.
Using that, you get:
1) given: r(t)=(2+t^2, 3t)
2) v(t) = d r(t) / dt = (2t, 3)
3) a(t) = d (v(t)) / dt = (2,0)
Answer: option </span><span>b) v(t)=(2t, 3) ; a(t)=(2, 0)</span><span>
