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 of the suitcase, you can use the formula KE = 1/2 * m * v^2.
Given:
Mass (m) = 14 kilograms
Speed (v) = 2.7 meters per second
Plugging in these values into the formula:
KE = 1/2 * 14 kg * (2.7 m/s)^2
= 1/2 * 14 kg * 7.29 m^2/s^2
= 102.06 Joules
Therefore, the suitcase has a kinetic energy of 102.06 J just before it hits the floor.
