Homework Statement
According to the Guinness Book of world records. the highest rotary speed ever attained was 2010 m/s (4500 mph). the rotating rod was 15.3 cm (6 in.) long. assume that the speed quoted is that of the end of the rod.
a) What is the centripetal acceleration of the end of the rod?
b) if you were to attach a 1.0 g object to the end of the rod, what force would be needed to hold it on its own.
Homework Equations
ac=v^2/r
fnet=m(ac)
The Attempt at a Solution
ac=2010m/s^2/7.56
ac=528117 that just seems ridiculous for an answer.
fnet=1.0g(528117)
fnet=528117
