I need to know what equations to use!
(A)How much work is done moving a 2.0Kg book to a shelf 2.00m high? (B) What is the change of potential energy of the book as a result? (C) How much kineetic energy will the book have as it hits the ground when it falls?
use mgh to calculate the gravitational potential energy
If the book falls 2.00 m to the ground then it will hit the ground with kinetic energy that is the same as the gravitational potential energy at the top.
(note it is kg and not Kg)
what is a tool used to determine the force of push or pull
