A bullet of mass \( 10 \mathrm{~g} \) moving with a speed of \( 20 \mathrm{~m} / \mathrm{s} \)
\( \mathrm{P} \) hits an ice block of mass \( 990 \mathrm{~g} \) kept on a frictionless

W floor and gets stuck in it. How much ice will melt if \( 50 \% \) of the lost \( K E \) goes to ice? (Initial temperature of the ice block and bullet \( =0^{\circ} \mathrm{C} \) )
(1) \( 0.001 \mathrm{~g} \)
(2) \( 0.002 g \)
(3) \( 0.003 \mathrm{~g} \)
(4) \( 0.004 \mathrm{~g} \)
