Abook of mass m is projected with a speed v across a horizontal surface. the book slides until it stops due to the friction force between the book and the surface. the surface is now tilted 30°, and the book is projected up the surface with the same initial speed v. when the book has come to rest, how does the decrease in mechanical energy of the book-earth system compare with that when the book slid over the horizontal surface?
