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