While chasing an armed suspect into an ice rink, a police constable is shot. Fortunately, the constable is wearing a bullet-proof vest which absorbs the bullet. If the muzzle velocity of the bullet is 350 m/s and its mass is 100 g. Find the final velocity of the constable and bullet if her mass is 69.5 kg. (Assume all motion is in a straight line and ignore friction. Assume that the constable is at rest. Provide an Illustration.)
