The formula to calculate kinetic energy is given as:
Kinetic energy = 1/2 * mass * velocity^2
Given:
Mass = 14 kilograms
Velocity = 2.7 meters per second
Plugging in these values into the formula, we get:
Kinetic energy = 1/2 * 14 kg * (2.7 m/s)^2
Kinetic energy = 1/2 * 14 kg * 7.29 m^2/s^2
Kinetic energy = 102.06 J
Therefore, the suitcase has 102.06 J of kinetic energy just before it hits the floor. Answer choice: 102.06 J.
