Puzzle Elements[edit | edit source]
Flavortext - Geez, kid. You're the most enthusiastic intern we've ever had, but this roller coaster design needs a lot of work. Back to the drawing board... J
Hint in Flavortext - A very subtle hint, but the "Geez" at the beginning is meant to clue at the usage of g as the unit of acceleration of choice for this puzzle.
Knowledge Required (Physics) - The majority of this puzzle involves calculations using centripetal acceleration (
a = v2/r) and conversions between potential and kinetic energy (
mgh = (mv2)/2). At each place where the roller coaster experiences acceleration (at the bottom of a loop, at the top of a loop, and during sections of free fall), calculate the acceleration in terms of g.
Alphanumeric Extraction - The accelerations turn out to be (within rounding error) integer multiples of g, where the integer is at most 26. Converting these to letters yields the answer to this puzzle.
