The Fast and the Furious

There are two men that meet in Chicago and both saw each others car and thought that both had a faster more powerful car; so they both decide to race cross-country and see who can travel the most distance by the time they meet.

The men start off on the east and west coast, so the men call each other and told them they were both there. So the one on the east coast started off and 120 miles per hour, and the other starts off at 100 mph, assuming they didn't have to stop to fill up for gas, where do they meet?

Rendezvous

A Car in Los Angeles starts toward San Diego on I-5 South at 40 miles an hour. Fifteen minutes later a motor bike in San Diego starts towards Los angeles on I-5 North - 120 miles away - at 55 miles an hour.

Which vehicle is nearest to Los Angeles, when they meet ?

Magnetic "Perpetual" Motion

In attempts to invent a "perpetual motion" machine the magnet and its power have played a role of no mean magnitude. Ill-starred "perpetual motion" machine inventors have tried might and main to apply the magnet to this end. Here is one such project described back in 17th century by Englishmen John Wilkins, the Bishop of Chester.

A Powerful magnet A is placed on the top of the pillar leaned against which is two inclined grooves M and N, one above the other. The upper groove M has a small hole C at the top, while the lower groove N is curved.



The inventor claimed that the arrangement would operate as follows. A small iron ball B was to be placed on the upper groove. Attracted by the magnet A, it ought to roll upwards. On reaching the hole, it should roll down, be carried up by inertial along the curve D, and find itself again on the upper groove M, from whence, again attracted by the magnet, it should again roll up and drop through the hole, roll down and on to the upper groove, ad infinitum.

This the inventor conjectured, would produce "perpetual motion".

Why does Rocket Go Up ?

Professor Feynman was teaching the class.
"Even from students of physics one may often hear a totally wrong explanation of a rocket's flight. They claim that it goes up by thrusting itself away from the air with the help of gases formed from gunpowder combustion. That incidentally is what ancients thought-rockets are invented long, long ago."

He added "But if we were to fire a rocket in an airless void it would fly, and even better than in the air."

What's the right explanation ?
