    A. What is the astronaut's centripetal acceleration during the first 20.0 s?

    Sorry for the confusion, Here is part B. How many g's of acceleration does the astronaut experience when the device is rotating at top speed? Each 9.80 m/s^2 of acceleration is 1 g. Do I need to find the velocity at top speed and then divide it by 9.8 ? How do I find the velocity at...

    A. What is the astronaut's centripetal acceleration during the first 20.0 s?

    Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 20.0 s to speed up from rest to its top speed of 1 rotation every 1.10 s. The astronaut is strapped into a seat 5.60 m from the axis. A. What is the astronaut's tangential acceleration during the...
