Tom has a meter stick which is marked off in centimeters (cm). He measures a distance three (3) times and gets measurements of: 11.52m, 11.51m, and 11.51m. A later calibration of the stick
shows it to be actually 1.001m long (1mm too long). Tom's friend Bill also has a meter stick but
it's marked off in millimeters (mm). He measures the same distance three times also, and gets:
11.452m, 11.451m, and 11.451m. A later calibration of his stick shows it to be 1.05m long (5 cm
too long)

In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. the cylinder begins to rotate about a vertical axis. then the floor on which the passengers are standing suddenly drops away! if all goes well, the passengers will “stick” to the wall and not slide. clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. part a what is the minimum rotational frequency, in rpm, for which the ride is safe? express your answer using two significant figures. f f = rpm
