    The students are members of a production team for a television series. Their first task is to respond to a question sent in by one of their viewers, who has asked, "Can the impact of a bullet cause a person to be propelled over a distance of a few metres?" In order to answer the question correctly, the production team will need to determine the gangster's velocity after impact with the bullet, as well as the amount of energy dissipated in the collision between the gangster and the bullet.
