At a carnival, you can try to ring a bell by striking a target with a 9.10-kg hammer. In response, a 0.410-kg metal piece is sent upward toward the bell, which is 5.15 m above. Suppose that 24.0% of the hammer's kinetic energy is used to do the work of sending the metal piece upward. How fast must the hammer be moving when it strikes the target so that the bell just barely rings?
