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?

  • Physical Science - ,

    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)

  • Physical Science - ,

    what is a tool used to determine the force of push or pull

  • Physical Science - ,

    54
