To calculate the potential energy gained by lifting the suitcase onto the bench, we can use the formula PE = mgh, where m is the mass of the suitcase (14 kilograms), g is the acceleration due to gravity (approximately 9.8 m/s^2), and h is the height of the bench (40 centimeters or 0.4 meters).
PE = (14 kg)(9.8 m/s^2)(0.4 m)
PE = 54.88 J
Therefore, the potential energy gained when Nan lifts the suitcase onto the bench is 54.88 J.
