## Homework Statement

Acceleration experienced by an astronaut in a rotating space station.

## Homework Equations

What force would he experience is his own rotating frame of reference.

## The Attempt at a Solution

Newton's second Law for a rotating frame is:

m

**r**'' =

**F**net+

**F**cor

**+ F**cf

**F**net (In the innertial frame) = m

**a_**c (centripetal acc)

**F**cor = 2m(

**r**'x

**Ω**)

**F**cf = m(

**Ω**x

**r**)x

**Ω**

I saw online that the answer was just the centrifugal force since the astronaut feels like he is being pushed away. However I do not understand why is it only that one and not

**F**cor

**+ F**cf , so I am confused on how to understand the motion. From his view, he is not moving (the station wall is pushing back on him) which I would think of that to be

**F**net , but if he isn't moving in the rotational frame so what is the acceleration

**r**'' describing.
