1.	A bullet fired into a fixed target loses half of its velocity after penetrating 3cm. How much futher it will penetrating before coming to rest assuming that it faces constant resistance to motion.
Answer» Given that its SPEED DECREASES from V to v/2 after TRAVELLING =3cm acceleration of bullet=vsquared-usquared --------------------------=a 2s
