To calculate the potential energy gained by lifting the suitcase onto the bench, we can use the equation PE = mgh.
The mass of the suitcase is given as 14 kilograms and the height of the bench is given as 40 centimeters, which is equivalent to 0.4 meters.
PE = (14 kg)(9.8 m/s^2)(0.4 m) = 54.88 J
Therefore, the potential energy gained by lifting the suitcase onto the bench is 54.88 Joules.
