Guest rikky Posted December 3, 2003 Posted December 3, 2003 I have a question about Inertia. You know how when you drop a peice of toast, it lands buttered-side facing upwards? And when cats jump from like high ledges and heights, they always land on their feet? Well, I was wondering: If I was to stick a peice of toast (butter-side up) to the side of a cat, and hurl it off a 9floor balcony from a hotel, would the cat rotate rapidly and propel itself upwards into the air (thus causing inertia), and then these buttered cats would become another form of transporation? Let me know what you think
fafalone Posted December 3, 2003 Posted December 3, 2003 The moment of inertia of a solid object such as a cat or a buttered piece of toast is dependent on mass. Since the toast has a negligible mass compared to the cat, its moment of inertia does not contribute to the total moment of inertia of the system, hence the toast can be ignored and the cat would just go splat.
Sayonara Posted December 3, 2003 Posted December 3, 2003 Let's assume the toast has the same mass as the cat.
blike Posted December 3, 2003 Posted December 3, 2003 What exactly does this have to do with inirtia, anyways
fafalone Posted December 3, 2003 Posted December 3, 2003 The component of kinetic energy that allows for rotation is 1/2Iw2, where I is the moment of inertia and w is the angular speed.
YT2095 Posted December 4, 2003 Posted December 4, 2003 can we at least come up with something ORIGINAL! that old chestnut is older than Gods Dog! despite the fact is has sweet F.A to do with science, and doesn`t even deserve a response. WHY do you ask?
