How can I explain scientifically that in the Simpsons movie, riding around the dome is actualy impossible?
Okay so if you’ve seen the simpson’s movie, you’d know that Homer and Bart have to ride on a motorbike around the dome to try and throw the bomb out. But really it can’t be possible considering the bike is moving so slow, and the dome is so big. Right?
So I need help; I have a presentation for science at school, and I don’t know how to explain it kind of scientifically.
Please help me!
Calculate the velocity that they’d need to travel in a vertical circle that large. At the top, the centrifugal force must exceed gravity.
v^2 / r > g,
so v > sqrt (rg)
You know g. Estimate how big that dome is. How fast is that? Also consider the difficulty maintaining that much speed after climbing all the way up. The motorcycle must get not only the kinetic energy:
T = 1/2 mv^2 = 1/2 mgr
but also potential energy:
U = mgr
How long did the climb take? Divide the total energy by the time to get the power required. Convert that to horsepower and check how much a typical engine can deliver.

The World’s Fastest Indian $7.48 A movie that exudes affection and goodwill, The World’s Fastest Indian is an unabashed mash note to a lovely character from New Zealand’s recent past.

It’s the 1960s, and Burt has the utterly mad idea of takin… |

The Motorcycle Diaries (Widescreen Edition) $5.19 The beauty of the South American landscape and of Gael Garcia Bernal (Y Tu Mama Tambien, Bad Education) gives The Motorcycle Diaries a charisma that is decidedly apolitical. But this portrait of the young Che Guevara (later to become a militant revolutionary) is half buddy-movie, half social commentary–and while that may seem an unholy hybrid, under the guidance of Brazillian director Walter Sall… |
