An elevator is moving upward with a speed of \( 11 \mathrm{~m} / \mathrm{s} \). Three seconds later, the elevator is still moving upward, but its speed has been reduced to \( 5.0 \mathrm{~m} / \mathrm{s} \). What is the average acceleration of the elevator during the \( 3.0 \mathrm{~s} \) interval?
(A) \( 2.0 \mathrm{~m} / \mathrm{s}^{2} \), upward
(B) \( 5.3 \mathrm{~m} / \mathrm{s}^{2} \), upward
(C) \( 2.0 \mathrm{~m} / \mathrm{s}^{2} \), downward
(D) \( 5.3 \mathrm{~m} / \mathrm{s}^{2} \), downward
