The Physics of Christmas

[Admin]

All right,
So school has broke up and you have all your christmas shopping done and you are awaiting the day, but spare a thought for that poor man in red and consider the following points:
Over 1 billion households around the world to visit and no more than 24 hours to do the job in so
What is the average speed of a reindeer as it travels round the world?
Given the speed what is the specific heat capacity of sleigh and reindeer fur to prevent them becoming a fireball due to friction?
What is the co-efficient of friction in the reindeer's hooves to stop themselves and the sleigh on a roof?
Given that the sleigh is heavy and the need for quick acceleration to high speeds what is the force for acceleration from the reindeer?
If reindeer can convert carrots into that much force why haven't we used carrots to fuel aeroplanes?
Given that the big red fellow has the odd tipple going from house to house, what is the legal drink and pilot sleigh limit?
What material is the sleigh coated with so that the Americans do not shoot it down?
How does the big red fellow know that we have all been good?
As usual answers on the back of an e-mail.
Merry Christmas
