In an amusement park ride called The Roundup, passengers stand inside a 18.0m -diameter rotating ring. After the ring has acquired sufficient speed, it tilts into a vertical plane,

Suppose the ring rotates once every 4.50 . If a rider's mass is 59.0 , with how much force does the ring push on her at the top of the ride?

Suppose the ring rotates once every 4.50 . If a rider's mass is 59.0 , with how much force does the ring push on her at the bottom of the ride?

What is the longest rotation period of the wheel that will prevent the riders from falling off at the top?

They make easy mistakes at adding, dividing fractions. Also about solving simple equations.
Some students learn these things quickly but some seem to repeat these mistakes over and over.
Example of mistakes: 1) (1/2)/7 is 1/14 and not 7/2 .
2) 1/(2x^(-3)) is x^(3)/2 and not 2x^(3).

H. A. Ray wrote a book entitled "The Stars: A New Way To See Them," which included a convenient table showing what constellation each visible planet could be seen in, at about the first of every month, across a number of years. But his planetary table in that book ends with the year 2006, and I wish I had a continuation. And everything I've found on the internet is either more complicated than I'd like to have ... like telling how to calculate the coordinates myself ... or is otherwise inconvenient ... like maybe giving a method for finding the precise location of a given planet at a given time, or is inconvenient in some other way, for the simple stargazer. Does anyone know of a table that's easy to read and essentially just a continuation of H. A. Ray's?
