To determine the distance of the book from the floor, we can use the formula for gravitational potential energy:
Gravitational Potential Energy = mass × gravity × height
Given that the potential energy is 196 joules and the mass of the book is 5 kg, we can rearrange the formula to solve for height:
height = Gravitational Potential Energy / (mass × gravity)
Substituting the given values:
height = 196 J / (5 kg × 9.8 m/s²)
Calculating the expression:
height ≈ 4 meters
Therefore, the book is approximately 4 meters above the floor.
