Compute how fast must the hammer be moving

Reference no: EM13646612

at a carnival you can try to ring a bell by stricking a target with a 9.00kg hammer in response a .4kg piece of metal is sent upward toward the bell which is 5.00m above. suppose that 25% of the kinetic energy is used to do the work of sending the metal piece upward, how fast must the hammer be moving?
