16. ( 3 points) The position of a particle on a line is given by \( s(t)=-3 t^{2}+6 t+5 \) where \( t \) is measured in seconds and \( s \) is measured in feet. Find the speed of the particle when \( t=2 \) seconds. \( \begin{array}{ll}\text { A }-6 \mathrm{ft} / \mathrm{s} & \text { (B) } 6 \mathrm{ft} / \mathrm{s} \\ \text { (C) }-1 \mathrm{ft} / \mathrm{s} & \text { (D) } 5 \mathrm{ft} / \mathrm{s}\end{array} \)
