A bullet fired into a fixed target loses half of its velocity after penetrating \( 4 \mathrm{~cm} \). How much further it will penetrate before coming to rest assuming that it faces constant resistance to motion?
a. \( 0.2 \mathrm{~cm} \)
b. \( 5 \mathrm{~cm} \)
c. \( 3 \mathrm{~cm} \)
d. \( 1.33 \mathrm{~cm} \)
