A book with 67 joules of gravitational potential energy fell from a shelf and landed on the flood. what was its kinetic energy when it landed on the floor?
67 joules. Gravitational potential energy becomes kinetic energy when falling.
To determine the kinetic energy of the book when it landed on the floor, we need to use the law of conservation of energy. According to this law, energy cannot be created or destroyed, only transferred or transformed from one form to another.
In this case, the gravitational potential energy of the book is converted into kinetic energy as it falls. The formula to calculate gravitational potential energy is:
Gravitational Potential Energy = Mass x Gravitational Acceleration x Height
Given that the gravitational potential energy is 67 joules, we need some additional information to calculate the kinetic energy. Specifically, we need the height from which the book fell, as well as the mass of the book.
Once you provide the height and mass of the book, I will be able to help you calculate its kinetic energy when it landed on the floor.
