What distance ia s book from the floor if the book contains 196 joules of potential energy and has a mass of 5kg?

The distance of the book from the floor can be calculated using the formula for gravitational potential energy: PE = mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity (approximately 9.81 m/s^2), and h is the height. Rearranging the formula to solve for h, we get h = PE / (m * g). Plugging in the values, h = 196 J / (5 kg * 9.81 m/s^2) ≈ 4 meters. Therefore, the book is approximately 4 meters from the floor.
