A bullet of mass \( 20 \mathrm{~g} \) is moving with a speed of \( 150 \mathrm{~ms}^{-1} \). It strikes a target and is brought to rest after piercing \( 10 \mathrm{~cm} \) into it. Calculate the average force of resistance offered by the target.
(a) \( 2500 \mathrm{~N} \)
(b) \( 2000 \mathrm{~J} \)
(c) \( 2250 \mathrm{~N} \)
(d) \( 2100 \mathrm{~J} \)
