If you exert a force of 4.5N on a book to slide it across a table and do 2.7J of work in the process how far have you moved the book?

To determine the distance the book has been moved, we can use the work-energy principle, which states that the work done on an object is equal to the change in its kinetic energy. Given that the work done is 2.7J and the force applied is 4.5N, we can calculate the distance using the formula for work: work = force x distance. Rearranging the formula to solve for distance, we get distance = work / force. Plugging in the values, distance = 2.7J / 4.5N = 0.6 meters. Therefore, you have moved the book 0.6 meters across the table.
