A spring gun of spring constant \( 90 \mathrm{~N} / \mathrm{cm} \) is compressed 12 \( \mathrm{cm} \) by a ball of mass \( 16 \mathrm{~g} \). If the trigger is pulled, the velocity of the ball is

(a) \( 50 \mathrm{~ms}^{-1} \)
(b) \( 9 \mathrm{~ms}^{-1} \)
(c) \( 40 \mathrm{~ms}^{-1} \)
(d) \( 60 \mathrm{~ms}^{-1} \)
(e) \( 90 \mathrm{~ms}^{-1} \)
