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 calculate the kinetic energy (KE) of the suitcase just before it hits the floor, you can use the formula KE = 1/2 * m * v^2, where m is the mass and v is the velocity (speed) of the suitcase.
Plugging in the given values:
m = 14 kg
v = 2.7 m/s
KE = 1/2 * 14 kg * (2.7 m/s)^2
= 1/2 * 14 kg * 7.29 m^2/s^2
= 51.03 J
Therefore, the suitcase has a kinetic energy of 51.03 Joules just before it hits the floor.
