Classical Mechanics
Level
3
A bullet is fired into a row of planks in such a way that it loses the same amount of kinetic energy for every plank it passes through. If the bullet loses \(5\%\) of its velocity after passing through the first plank, then what is the minimum number of planks required to stop the bullet?
