Question

The 20-g centrifuge at NASA’s Ames Research Center in Mountain View, California, is a horizontal, cylin- drical tube 58 ft long and is represented in Figure P4.29. Assume an astronaut in training sits in a seat at one end, facing the axis of rotation 29.0 ft away. Determine the rota- tion rate, in revolutions per second, required to give the astronaut a centripetal acceleration of 20.0g.

Answer 1

Just use the expression\[r \omega^2\] for the centripetal acceleration, where omega is the angular velocity.
