I have an example from my machinery handbook which shows the kinetic energy of a pile driver and shows it will drive a pile some distance at a force until the energy is expended.
The formula is (Average force of blow times distance)= Weight of object (driver) times distance it falls)
Just curious, what slows down the driver as it hits the pile? Is it the loss of energy, or the reaction force from the pile, or both? It has to be both right?
As it does the work, it is expending the energy due to the reaction force trying stop it? Maybe someone can help me understand this situation.
Thank you
