How much kinetic energy does a book have just it hits the floor?

Just about as much as it had potential energy before it started falling - since most of the potential energy will be converted into kinetic energy. The exact amount depends from how high it falls.

What happens to kinetic energy of a falling book when the book hits the floor?
turns into vibration and heat energy.
How does the falling mango change it's energy conversion?
Well. I'm no physicist. BUT. I think its potential energy, which then changes to gravitational energy. OR. Its a mango. When it falls. It hits the floor. And smashes. What a waste of a mango.
What device that transforms gravitational energy to kinetic energy?
Anything that falls. Some examples are: -- A waterfall -- A ball rolling down a hill -- A sailplane, when it is NOT climbing in a thermal -- Any pendulum, when it is moving TOWARD the center of its swing -- Anything you drop. The gravitational potential that it has relative to the floor while you're holding it in your hand is exactly the kinetic energy it has when it hits the floor.
What energy transformations occur when a gun is shot?
•Kinetic in the firing pin - chemical when it hits the primer- turns back into kinetic(both ways), light, heat, and sound energy - hits the target kinetic, light and sound.
What sort of energy does a book have if it falls off a high shelf?
Before it falls it has gravitational potential energy. While it falls, the potential energy gets converted to kinetic energy. Part of this gets dissipated by friction - mainly converted to heat. Once it hits the ground, all the energy will be converted to heat.

What happen to the kinetic energy of a falling book when the book hits the floor?
when book is dropped from the height its kinetic goes on increasing and the sudden stop to the book when it touches the ground all the kinetic energy of the book is converted into potential energy of the book which helps the book to be stable after the impact, in short when the book hits the ground kinetic energy is converted to potential energy due to law conservation of energy.
When a book falls to the floor what happens to the potential energy?
When you drop a book the original potential energy is converted into the kinetic energy, When the book hits bottom the kinetic energy is absorbed by the surface underneath and some is converted to sound energy. This maintains the law of conservation of energy. the total amount of energy in this universe is constant and remains constant. Energy can neither be created nor destroyed it can just change its form from one form to another.

Describe a stone falling off the tabletop in terms of both kinetic energy and potential energy?
Sitting on the table the stone has potential energy, relative to the ground, of weight times height, mgh. It has zero kinetic energy so its total energy is E = 0 + mgh. When it begins falling it loses potential energy (as it loses height) and gains kinetic energy ( as it picks up speed) so the sum stays the same as initially E = KE + PE = mgh. Just before it hits the ground all of its potential energy is gone and has been transformed into kinetic energy. So the kinetic energy at the bottom (1/2)mv^2 will equal the potential energy at the top.

What is the kinetic energy of an object weighing 65 kg dropped from a height of 40m?
Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.
When might kinetic energy turn into sound energy?
When you drop a rock and it hits the side walk it makes a sound. Kinetic energy transferred to sound energy.

What forms of energy is there when the baseball is rolling when it hits the ground?
As the baseball is falling, it still has a lot of the kinetic energy that it got from the bat, and it keeps picking up more kinetic energy from gravity until it hits the ground. Once it hits the ground and rolls, it steadily loses kinetic energy to push grass out of the way, and to slightly heat some grass with friction by rubbing against it, until its kinetic energy is all used up and it stops rolling.
What type of energy transforms when a ball rolling off a table bouncing on the floor until it stops?
when the ball is rolling off the table the ball currently has only Kinetic Energy (KE=1/2*mass*velocity^2). When it is falling of the table it both potential energy(PE=mass*gravity*height) and kinetic energy. The potential energy is basically the energy that gravity can "potentially" can act on it and the kinetic energyis the speed of the ball at that time. It has Kinetic Energy in both the x and they y directions. The velocity in the x direction is from the speed that the ball had before it fell of the table - the force of wind resistance. The velocity in the y direction is the speed that is gained from gravity. Once it hits the floor the potential energy is 0 and it only has kinetic energy. When it bonces back up it has both potential and kinetic energy again and this continues each time the ball bounces back up until it has stopped bouncing and and is only rolling The height that it bounces depends on the spring contanst of the floor
