A worker drives a 0.5 kg spike into a rail tie with a 2.5 kg
sledgehammer. The hammer hits the spike with a speed of 65 m/s.
If 1/3 of the hammer's kinetic energy is converted into internal
energy, how much does the total energy increase?

Answers

Answer 1

The increase in internal energy will be 1760.42 J.

What is kinetic energy?kinetic energy is the energy of motion, observable as the movement of an object or subatomic particle. Every moving object and particle have kinetic energy. A person walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field are all examples of kinetic energy at work.The energy of a body due to its motion is called kinetic energy. - Every object around us which is moving possesses kinetic energy.Kinetic energy (KE) is the energy of a body in motion, which means it's essentially the energy of all moving objects. It is one of the two main forms of energy, along with potential energy, which is the stored energy contained within objects at rest.
