Consider a general aviation airplane that weighs 3000 lb with a designated approach speed over the runway threshold of 65 kts., calculate the KE. Now, consider if that same airplane approaches the runway with an extra 10 kts. of speed due to poor planning, calculate the new KE.

Why does only a 10 kts. change in approach speed result in such a wide margin of KE? What are the consequences of this “extra” energy?
