Nan’s suitcase is on a bench. The suitcase has a mass of 14 kilograms. Nan accidentally knocks the suitcase off the bench, and the suitcase falls at a speed of 2.7 meters per second. How much kinetic energy does the suitcase have just before it hits the floor?

To find the kinetic energy, we can use the equation KE = 1/2 * m * v^2.
Plugging in the given values, we have KE = 1/2 * 14 kg * (2.7 m/s)^2.
Calculating this, we get KE = 1/2 * 14 kg * 7.29 m^2/s^2.
Simplifying, we have KE = 102.06 J.
Therefore, the suitcase has 102.06 J of kinetic energy just before it hits the floor.
