A 56.7g steel ball is shot from a spring gun into the 203g pendulum of a Ballistic pendulum. The pendulum swings aside and is kept'at its maxīmum height by mechanical means. The change in height is measured to be 13.1cm. a) What is the velocity of the steel ball when fired from the spring gun? b) The pendulum is then swung aside, and the gun is placed on a table șo that it can be aimed horizontally to fire the ball into the room. If the ball leaves the gun at a height of 1.12m from the floor, how far does it travel horizontally before hitting the floor? 7.69*. h an introductory laboratory experiment, a 56.7-g seel ball is shot from a spring gun into the 203-g pendulum of a ballistic pendulum.
