In the fabled mines of Moria a dwarf drops his axe down a deep well. The axe starts at rest and during each second of fall, the axe gains speed by 5 meters per second. What is its velocity after 2 seconds? And after 5 seconds? Show your work! If it takes 20 s for the axe to hit the bottom, then how deep is the well?
