A 17-kg suitcase falls from a hot-air balloon that is floating at a height of 333 m above the surface of Earth. The suitcase has an initial speed of 0 m/s however it reaches a speed of 26 m/s just before it hits the ground. Compute the percentage of the initial energy that is "lost" to air resistance.
