How does the book kinetic energy

Reference no: EM131019785

Imagine a book that is falling from a shelf. At a particular moment during its fall, the book has a kinetic energy of 24 J and a potential energy with respect to the floor of 47 J.

(a) How does the book's kinetic energy and its potential energy change as it continues to fall?

(b) What is its total kinetic energy at the instant just before it strikes the floor?
